sbiddle:
rixth: sbiddle: keep in mind that the 780G has been praised for being an excellent http://www.silentpcreview.com/article807-page8.html

Playing this clip: http://www.apple.com/trailers/newline/rushhour3/hd/ (1080p | 24fps | ~10mbps) used only 12% of the CPU when it was underclocked to 1.5ghz. I can't imagine TV 3 is going to be 9 times as demanding.

Maybe not 9 times - probably about 10x more demanding! Our H.264 broadcasts are nothing like the QT trailers.

If you go down the ATI path it's at your own risk - there are know issues with all ATI 2xxx/3xxx cards and even the 780G chipset with hardware accelerated H.264 interlaced content. I've spent hundreds of $$ trying various combinations before I realised an Series 8 or 9 NVidia (8500 or greater) is the only way to go. If you buy ATI I just about guarantee it won't work well.

Or it will work just fine. (GA-MA78GM-S2H)

Oh, and the Athlon 4200+ x2 can do TV3 without hardware acceleration and if you aren't doing anything else it won't drop frames, but it will have a big jitter so it's not quite smooth but perfectly watchable, it shows at about 50% CPU usage on average (over both cores).

I will admit though, sometimes i'll change to a channel, one of the low def ones especially and it will be corrupted, switching channel or rebuilding the graph will fix it. Sometimes corruption spreads to Vista Aero.

Are you using dvbviewer?

If so, check view>filters>VMR9 renderer and see what the jitter says, with EVR it's 0 but with VMR9 I get 20 milesecs+, it's enough to give it a slight lack of fluidity.

Thats why I don't use Vmr9, I just use overlay mixer.

Got my replacement parts via CourierPost (not post haste!) today, big thanks to the lovely folks at pconlineshop.co.nz.

I can decode the TV3 samples that are on geekzone fine, fast forwarding and rewinding works okay too. But as I don't yet have a tuner card (must save a little more) I am unable to test chaning channels.

PcOnlineShop sent me a 4600+ instead of a 4200+. I have OC'd it to the level of a 5600+, it runs wonderfully!

Will report back once I get a tuner!.

Tom.
