another h.264 issue

[jzrile]

Hi there!

Our national television (Croatia) started to broadcast DVB-T signal in h.264 format (mostly EURO soccer championship games). That's the reason I've bought AVerTV Speedy PCI-E H788A Hybrid card. I didnt' have any luck with Avermedia software for h.264 broadcast, mpeg2 works fine. I've tried to use GBPVR with several decoder combinations - CoreAVC, Cyberlink PDVD 8 etc. I have best results with Cyberlink codec. H.264 broadcast is watchable until game starts then problems occur - picture slows down or breaks. I suppose that games have higher bitrate/stream. My current configuration is Windows XP, C2D E6600 2.4GHz, 2GB RAM, nVidia 7600GT, latest drivers. My question is: will I get better results with 8600GT or 9600GSO with purevideo 2 support? Does anyone have any other idea?

Thanks everyone.

It does sound like its related to the higher bitrate or resolution used by the actual game, so you would probably benefit from hardware h.264 accelerating videocard like those you mention above.

From my own experience, you will want to stick with Nvidia, 8600GT will do all you want unless you wanted some gaming capability as well. I use 9600GT's and they work pretty well for me.

The parts listed look fine. The 7600GT is basically an 8600GT minus DX10 and the UVD chip for h.264. I had no problems with 1080 HD h.264 with a 1.6ghz Core2Duo and a 7600GT. But I never used it with a live TV feed, so maybe that causes other issues.

If you install Rivatuner, it should show you how much GPU is being used. I'd be surprised if the 7600GT isn't a fast enough card.

I wouldn't put hopes on Purevideo. It's good when it works, but that's only half the time, imo, so it's hardly worth a bother.
