Well, xvmc uses much help from the nvidia card, definately helps out when you 
want to show 1920x1080 material. Having said that, if you disable the tvtime 
postprocessing, you should be able to run 1920x1080 without xvmc. I do it 
without any problem on my htpc, which carries a 2.6GHz P4 onto a 5700Ultra. 
But there's not too much headroom using xv. Yes the htpc is optimised for 
just that (gentoo) but it runs 1920x1080 ts material flawless. 

I have not tried this with live streams though, but I have a lot of hdtv 
material on my server, including some from euro1080. 

A lot of things can be said about nvidia, but their xvmc support is quite good 
imho. And I have tried a lot of graphics cards for my htpc. Some people finds 
the cheaper fx5200 cards a bit washed out on colours, but it all boils down 
to what kind of output device you have. ymmv.

You guys must miss out on something! I would be *very* surprised if a amd64 
3000 would not do this easily! I bet you have too much post processing 
enabled! Remove it, you shoudn't really need it with hd material anyways.
Or you must have graphics card from stone age/with bad drivers.
