Hmm, that has not been my (admittedly limited) experience. My 2GHz
Core 2 Duo cannot play back even low bitrate 1080p without frame
dropping (mplayer, vo xv). My only two vdpau cards I've used are a
8400 GS (until the fan blew up) and a 520, perhaps I wasn't coming
across much 1080p content whilst I had the 8400 GS.

The 520 certainly handles anything I throw at it, bluray, HD broadcast, rips...

Thanks for the info
