I think that's a good idea. VDPAU may still be a bit too cutting edge
for comfort, but support for it is bound to improve, and HD is still
cutting edge in VDR in general (I haven't heard of anyone releasing a
patch for the BBC HD audio pid problem yet).
I chose a 4850e too. At first I tried ATI 3200 onboard graphics, like
you thought of, but it was dreadful, very unstable with ATI's fglrx
driver, while the open radeonhd driver doesn't even support Xv on it yet
AFAICT. I replaced it with an NVidia 8200 based board. I think there's a
performance problem with the 177 series nvidia driver on basic
acceleration, but it's fine with Xv and OpenGL, stable, and hopefully
the performance is fixed in 180. I haven't tried VDPAU yet.
IME the 4850e can playback 720p H.264 quite easily, but can't manage
1080i from DVB. It might be trying to run a deinterlacing filter that
pushes the demand over the limit. I'm quite disappointed that they
standardised on 1080i, even for movies by the look of it, instead of
