Don't know where to from here ... any suggestions?


Well, Powercinema 6 works fine for me on Vista. You could give that a blast...

Gemini: Hi



I also have a 780G and have been trying to get Freeview working under Win 7.

Green, pixelated or no picture on some channels in Media Centre.



Advice was to install Mediaportal and PowerDVD6.

Mediaportal is installed but is not working properly. It is very slow and is locking up. Have no idea why.

It also is not detecting my Hauppauge USB tuner.

I'm thinking installing PowerDVD is not going to fix these problems :)

Running ATI Catalyst 9.5 driver only.

Now that the UK has switched to H.264 broadcasts on Freeview, more and more people are running into the same issues as reported on this thread: http://thegreenbutton.com/forums/thread/332422.aspx


A Microsoft PM puts it clearly: "To get H.264 working, I recommnend AMD 4 series or newer and NVIDIA 8 series and newer." So that effectively rules out the 780G chipset unless you use an external video card.

Funny how what works on XP and Vista with the HD3200 may not work on Win7, don't you think? Although he does say that "older cards such as the HD2400 don't support DXVA for h264"

Clearly the HD3200 (780g) does support DXVA, based on my experience. By all means shell out for an extra 4x AMD or 8x NV if you want, but it is by no means necessary for hidef in NZ.

Unfortunately those graphics cards aren't an option in a low profile low power HTPC case

I have this card: http://www.ascent.co.nz/productspecification.aspx?ItemID=374919

It comes with a low profile replacement bracket and is passively cooled.

So could you not get Freeview working without that card on your Vista Mediaportal 780G?

I got it working fine in Vista, I was just giving you an option on a new video card if you can't the onboard one working in W7 :) I'm going to do an upgrade of my HTPC to W7 shortly, but will be sticking with MediaPortal.

I couldn't get the deinterlacing working as smoothly as I'd like with the onboard video (I'm using the PowerDVD8 codec with h/w decoding turned on with a low power CPU). I was getting a bit of stuttering, and it could just be my imagination but I found the picture looks slightly better with the 4550, I also found you get more deinterlacing options in the Catalyst Control Center (which could explain the better looking picture).

So where is the Add/Edit capture cards option in Mediaportal?
Online help talks about it but no instructions/screenshots about it

It should automatically show up on the list of available tuners. If you've just installed the drivers for it you might need to restart the TV service (do this through services.msc).

As a bit of encouragement to 780G users, I'm using a Gigabyte 780g board, 7750 CPU, PDVD8, Vista and Mediaportal. Have no stuttering or picture problems with live or recorded TV. The picture looks way better than anything i've seen in the shops e.g. external or internal decoders. Upgrading to the HT3 processor recently opened up all the options in ATI control centre for deinterlacing and made a noticeble improvement.

Mediaportal doesn't recognise my Hauppauge 900H USB tuner, is very slow to start up and locks up in the menu screen ... why do I need it again?

Yeah I've got an 8650 in a basically identical setup to yours and it all looks marvellous, I agree that the extra video options available on the HT3 processor add that extra layer of quality. It's nice to have a bit of grunt in the CPU department for encoding things as well.

Interesting, what sort of cooling have you got on your CPU? I have the Athlon64 4850e (45W) and I get away with a Skythe Mini Ninja with the fan removed with the 2x 120m case fans sitting next to it, the CPU never gets above 25C. I'd like to add a bit more grunt but I don't want to add more fans.

I've got an Antec Fusion v2 case, I'm using the stock 2x120mm fans on the right hand side of that case turned down to their lowest setting, and the stock CPU cooler that came with the 8650 with whatever goo it came with. I figured I'd start messing round with it if it ran too hot, but it's been fine so far (2 months or so).

The CPU gets up to 51C if I run a long encode, but never above, and it never gets unstable. I'd like to swap the 120mm fans for something a little quieter - possibly some sort of control board to make them run a bit slower would do the trick, as they're really very quiet now but not silent :)

The only issue I really have with it at the moment is that those fans are pulling so much air through the case they're dragging in dust and some of it is sticking in the front USB/Firewire ports! Some blanking plugs or maybe sealing up those ports at the back might be in order.

I have the Antec NSK2480B which has a very similar layout to the Fusion, but it doesn't look as nice (I wish I had have spent that bit extra!!) I ended up replacing the two Antec 120mm fans with Scythe slipstreams running at 800rpm (about $30 each). They move 40cfm and are only 10dBA, and I also replaced the fan in the PSU with the fan from the Scythe Mini Ninja.

I'm definitely tempted to upgrade my CPU as the 4850e I have is only HT1.0. I'm still trying to comprehend the differences between all the models, but I believe there's a Phenom X4 that's only 65W, I might be able to get away with passive cooling with that.
