I have:

Athlon 64 3200+
Asus MB
pchdtv HD3000
Nvidia FX5200
MythTV R5A15.1

I'm finally able to get proper signal strength and record HD content but the playback isn't 100% smooth. Should the content be decoded by the main processor or my video card?

Any tips for improving playback are appreciated.

Tell us what you did to set it up, then we can help.

you don't want to use xvmc, but you do want to load the nvidia drivers. and you probably want to go to libmpeg for playback.

Thanks for the replies. I swapped out the Nvidia card for a Radeon 9250 (should be faster anyway, right?). Before I did that, it was actually playing smoothly for a while. I added a modeline to have the correct resolution, and that seemed to do it.

Now that I have the Radeon in, it's back to choppy. Do I need to load special ATI drivers?

If you are hell bent on keeping the ati I would probably load the ati drivers, but my suggestion would be rip the ati out and put the nvidia back in. The nvidia drivers in linux are such that a 4 year old nvidia card is better to have (particularly for this type of mulitmedia) than the latest and greatest ati card. Maybe one of these days ATI will get of thier duffs and make a decent driver, but for now I say stick with nvidia.

I was having stuttering issues when I configured KM-R5A15.1 on a Sempron 3000+ and GeForce2 MX 400 with 64mb memory.

Then I simply upgraded to 7174 driver and all the stuttering went away !!!

I went back to the nVidia card and now it's fine except on PBS, for some reason. It's not a reception issue... the images look great, but are very slow. I don't care that much since the only reason I'd watch PBS is to see how great HD looks, because they broadcast in it 24/7

well could be that PBS is broadcasting in 1080i and the other stuff is 720p. with my older cpu I could watch 720p smoothly, but not 1080i. but I would think yours should be able to decode 1080i smoothly as long as nothing else is happening on the box. have you tried recording pbs and just playing it back while nothing else is going on. to see if just that little bit makes it play smoothly. you really are on the very bottom rung of what will playback hdtv.
