Thanks for reporting back SamF! :)
So did they explain the whole bitrate thing in any greater detail, or did they just say "the card is faulty and can't be used in NZ"?

This is the email I got from them:

Dear sir,

Sorry for late replay,It look like hardware issue and currently we are no more selling this TD-500 in New Zealand market.
in the mean time you may send the card to singapore office we will replace another model WINTV-HVR2210 it is a PCI-E card.
is it ok for you?if ok we will issue an RMA number to send your TD-500 card to singapore office.

Hi all. I have been trying to solve a separate issue which I started a new thread for.
Here http://www.geekzone.co.nz/forums.asp?forumid=84&topicid=90588

Swapping out the Avermedia card so I have a Hauppague HVR4400 & HVR2210 has solved the multiple offset channel entries I was getting when scanning tuners. Please post any comment regarding this on the other thread.

My video is now mostly stable. I still occasionally get a small amount of pixellation which seems to occur about 30 seconds after changing channel or 30 seconds after skipping through adverts in a recording. No video Stutter. Also the video still isn't as smooth as it should be. I think someone else was having the same "pixelation 30 second after issue"?

I now have 3 UHF and 1 satellite tuner.

Some hints for others with multiple tuners.

1. If you have a satellite tuner & UHF tuners you can merge them and use the Satellite Guide data.
2. If you have multiple tuners you can force media centre to obey pre & post record padding and use multiple tuners for adjacent programs by setting recording defaults to Start when possible "2 minutes before" and Stop when possible to "10 minutes after". Then when scheduling a recording or series edit the schedule and change the "10 minutes after, when possible" to "10 minutes after". This forces media centre to obey the pre-post padding. This important bit is the "10 minutes after". Less than 10 minutes or using "Where possible" won't enforce padding.

Regards Allen.

Hi NZ255 and everyone else,

I purchased a Palit GT440 Nvidia 1GB DDR5 PCI-e Graphic Card and was able to install it into the computer this weekend. I completely disabled the onboard video (6550D) and am running both screens through the GT440 (using the latest drivers from the nvidia website), a Dell Ultrasharpy U2212HM through DVI and a Plasma through HDMI. Both screens have a native 1920x1080p resolution.

I can't remember who the original poster was that said this in this forum but the differencve between the nvidia card and ati card is "night and day". I tested multiple Blu-rays through Power DVD 9 and Television both SD and HD through Windows 7 Media Center and it all looked fantastic! No artefacts on start up, no glitches, no jaggies and a much sharper and vibrant image. So I am very happy with the result and would like to thank you all for your persistance and support with my issues. I hope this may also help anyone else who has similar problems.

Thanks guys!! :)

That be me

Glad to hear you've got it sorted.

Do you have a slight glitch around 30 - 40 seconds after changing channel or after skipping through adverts? This is my last remaining video issue. Not major, just annoying.

Hi AllenG,

Thanks for your reply. I was actually only able to play around with Media Center for maybe an hour or so after everything else was done, but never did notice a slight glitch 30-40 seconds in. As the computer is with it's new owner I won't be seeing it again for another week or two to again check in on how it's going, but it did seem to be working well. Actually it was only really recorded tv that I kept viewing (as it was easy to remember how bad the programs looked with the ATI to compare them with the nvidia GT440). Do you only have the 30-40 glitch with livetv or with both live and recorded tv. If only with livetv then I would have to double check in a week or two and let you know, but I definitely had no glitch 30-40 secs in (or at all) with recorded tv that I have noticed.

One thing I did notice was after I installed the Graphic Drivers but had not yet installed the Southbirdge chipset/Sata Controller drivers I noticed that when I would play recorded tv or skip through programs it would glitch for the first second or so of playing and then carry on smooth, but once I installed all of the Chipset/Sata Controller Drivers it was completely smooth from every start and after every skip. I'm just wondering whether or not this may help you? By the way my Hard Drives are all set up AHCI and I have a Crucial M4 SSD for the O/S and recorded TV on it's own 2TB HDD, a Samsung Spinpoint F4 HD204UI. I installed the chipset drivers from the motherboard disc and the the latest graphic drivers from the nvidia website.

Thanks :)

Were there any southbridge chipset drivers installed at first (like windows default drivers) or were they 'missing'?

Hi SamF,

That is a good question...

I never actually checked if Windows had installed default chipset/sata controller drivers or not during it's installation process. I just installed the chipset drivers from the Motherboard CD after the graphic drivers and I did not install them through device manager or windows update. If it helps I never had the computer connected to the internet throughout the install process and it was a copy of Windows 7 Home Premium SP1 64-bit that was installed. Once I did actually install the chipset drivers from the CD it also popped up on the taskbar that the HDDs had each been succesffuly installed after the reboot and that an additional reboot was neccessary to complete.

Thanks, I hope that may help. :)

Hmm, might have to try that...

Win7 is pretty good at picking up drivers for hardware these days, but I guess it's a moot point really, you updated them so it doesn't really matter if they were present or not to start with.

I don't have any glitches when changing channel or skipping. I get minor pixelation for a part second 30 or so seconds afterwards. Not sure if this does it for all channels but it does do it for live & recorded TV. I suspect it occurs after viewing the EPG etc as well.

I'll try and note whether it's restricted to freeview ie H.264

As for Chipset drivers. I did download and install the chipset drivers from the ASUS website.

Regards Allen.

Updated my chipset drivers, no change.

Oh well, it was worth a go :)

Hi Allen,

With the nvidia card (GT440), I have experienced no such problems, knock on wood. I remember though with the old ATI 6550D that I would get a pixelated glitch pretty much bang on 40 seconds in after viewing recorded tv and live tv etc and also the picture would glitch if I resized the Media Center window smaller/larger/or full screen and it would occasionally do it when bringing up the guide also (not everytime though). It would also do a terrible glitch for 2 or 3 seconds when first viewing any tv as well (live, recorded, skipping, channel changing etc) that was driver related to the best of my knowledge.

I know the ATI 6550D has driver issues, but the glitch 40 seconds in to me I always thought it may possibly be a graphic card ram buffering issue perhaps? It would do it on all channels SD and HD, not all the time but most times. This was part of the reason why when I purchased the nvidia card I tried to purchase a model with DDR5 ram rather than DDR3 as I read somewhere that it can make significant differences for some programs such as MadVR (i think its called) when viewing high bitrate 1080p video with picture enhancement modes on and no dropped frames compared to the DDR3 version, which would drop frames. Even though I don't use MadVR I thought it couldn't hurt for Media Center.

As mentioned earlier, I will put the computer through a lot of paces in a week or two and if there are any slight glitches etc I will definitively let you all know.

To SamF,

yep, definitely worth a shot, sorry that it didn't help :(

Thanks :)

40 second symptom sounds exactly like what I am seeing.

The ATI card I just removed had DDR5 ram, unfortunately the GTX260 doesn't.

What brand of GT440 did you buy, the ASUS and Gigabyte ones listed on Pricespy are DDR3. I don't know much about the Palit brand? Is this your only graphics card? It seems like a low end card? ,but if you aren't gaming and it is doing the job then that's perfect. DDR3 aside, my GTX260 should be more than up to the media centre job

At little over $120 I guess a GT440 as a second card may be worth a try if it fixes the 40 second and frame dropping? Hmm. How many graphics cards can I collect?

Allen.

Hi Allen,

I would assume that a Nvidia GT260, with DDR3 should definitely be powerful enough for fluent Freeview HD so possibly there is another factor or a combination of factors involved that cause the 40 sec glitch when viewing recorded or live tv (either chipset, HDD, graphic ram, CPU, & drivers etc).

I had to search low and high for a GT440 with DDR5 as most of the DDR5 versions were not available in New Zealand. Palit seemed to be the only brand in New Zealand with a DDR5 version of the GT440. From what I have read Palit is definitely a cheaper brand and I would have prefered to have bought either an Asus or Gigabyte for example but as Palit was the only available brand I found what can you do... When researching the card I did read a small number of stories of people having an occasional pink screen flash before loading certain games, or an occassional few squares of odd colour on their desktop when first booting only with this particular branded card, but it has been working well for me so far, knock on wood :)

The reason i went for the GT440, was that others had stated good success with NZ freeview and the GT430. The GT440 as I understand it uses the same graphics chip but with faster clock speeds and also has the DDR5 option on some models. Other sites had also posted the GT440 as the minimum for particular programs (madVR) when viewing high bitrate HD with maximum video settings enabled. It also does not require any addtional power connector as it runs through the PCI-e power at about 65w i think so thats good for a HTPC and less cable clutter. Bear in mind that this card will take up two slot spaces on your motherboard and your PSU must have at least 22A on the 12V line. The fan on this card has been very quiet for me but i do have three fans doing a great job at expelling hot air from the case so results will vary I guess.

I purchased mine from Ascent as they have a reasonable retrun policy (just in case it doesn't work then I could return it), but there was stock also availble at elive and one or two other stores as well. It was about $145 incl delivery from Ascent.

Thanks, I hope this helps :)

Cheers.

Just for a laugh I've logged a technical support request with ASUS NZ for the ASUS EAH5770 ATI based card. Interesting to see what they have to say....

I think I'll live with what I have for now with the Nvidia.

May look at a dedicated PVR long term (or a prebuilt SFF media centre PC without win7 64bit?) but getting a multi-tuner one with Sat & UHF will be an issue.
