Hi there,

I've just moved out of town a bit and my DVB-T card wouldn't get a signal. So I've added a Hauppauge WinTV Nova-S Plus card.

I love (and hate!) my HTPC, and have run one for the last 4 years (first year or so in the UK before we moved back to NZ)

I'll start by saying that I probably know enough to be dangerous - but get a bit lost when the technical stuff gets too deep!!

My HTPC is based on a Asus M3N-H with integrated 8300 video chipset. It's run pretty OK with DVB-T for the last 18 months or so (little jerky on some channels but I put up with it). I figured that the DVB-S option would be a lot less intense on the system and hoped I could just drop the new card in and be away.

I run XP Mediacenter edition, but use MediaPortal (with TV Server) as my PVR software.

OK, so I installed the card, put on the drivers (off the CD), scanned for channels (Optus D1, LNB low = 10750, Switch 0, LNB High 10750). Picked up a hundred odd channels and added them into my guide.

When I try and view the channels, they do come up - but I get about half a second of sound / video, and a couple of seconds where it pauses. I guess I'd call it a bad stutter. Same thing happens on both TV channels and DVB-S Radio - could be an important point?

The satellite signal strength seems OK - when scanning I got pretty much full bars.

As I mentioned, previously this has been running satisfactory on DVB-T. I have Powercinema, FFDShow installed.

I've tried combinations of different Codecs by going into settings and changing them for My TV, but no luck. I haven't reset between Codec changes - I guess this isn't necessary? There seem to be about 8 different options in there and I'm not sure which would be the best choice anyway.

Can anyone out there give me some tips - bit of a step by step approach might be useful. Unfortunately, since we've just moved the internet isn't running at home yet either - so I won't be able to provide any more info! I'd rather not start from scratch - since all the DVD side of it's working pretty well (5 channel output via digital to my amp etc...)

By the way, I'm in (or just out of) Dunedin.

Much appreciated - thanks in advance!!

Danny

May not be the issue at all but when I first ran media centre I had issues that sounded very similar. I put it down to a bad signal and had a tech come out and check the dish but he could not find any issue and although he replaced the LNB there was no improvement.
In the end it turned out to be an issue with the slot that I have the tuner card in. Not that it was faulty just that it was sharing a IRQ with another couple of cards that were all high bandwidth users as well. I had to juggle around the cards until I could get all the high bandwidth cards on different IRQ's. Might be worth checking.
Also I would never use the drivers off the CD. Always get the latest available from the web site.

I didn't full on read all your thread... but have you tried recording to a video file, then taking that file to another machine, or using VLC or similar to play the file. It's it still jerky then, then it's most likely signal related. If not, then it's playback and you'llhave to fiddle with codecs etc.

OK, I'll try -

* Removing all other cards (DVB-T and Wifi) to see if that resolves the issue
* Recording some TV and playing back on another PC

I've also downloaded the latest drivers from Hauppauge website (here at work) and put them on a memory stick to take home.

I'll see how I go!

Thanks, much appreciated - and keep the suggestions coming!!

Update! Sorted out -

I shifted the cards around and it fixed the problem! In fact, I decided to take the DVB-T card out completely, since I won't be able to use it in the meantime anyway.

Funny though, now I have a remote control issue!! I've posted a new topic - http://www.geekzone.co.nz/forums.asp?forumid=84&topicid=64928

Thanks Nety and Psycik for your help...
