I don't have anything positive to say, but I'm using hardy and newerish
drivers with NvAGP set to 0 on an AMD 3000+ and 1080i works fine, but 720p
stutters horribly. So far I've just dealt with it and watched 720p stuff on
another front end, but long term I'm not sure if I'll attempt VDPAU with a
PCI card or upgrade the mobo/CPU finally. XvMC support is so annoying.
