Yeah, that stuff about 8400's being "designed for" AMD is garbage. For
the most part the 8xxx's and their corresponding 9xxx model are the
same architecture, sometimes with a die shrink as a result of a
manufacturing process change.
For playback of HD-PVR recordings, VDPAU acceleration is almost
essential. It will also allow you to use VDPAU's excellent
deinterlacing algorithms.
For MythTV purposes, consider:
With several limitations:
8400 GT
9400 GT
GT 210
(also Ion and Ion 2 systems fit in this category)
With some limitations:
8500 GT / GS
9500 GT / GS
GT 120
With very few limitations:
GT 220
With no limitations that come immediately to mind:
GT 420
GT 430
All of these cards provide suitably low heat / noise. I haven't listed
the faster cards because they're too hot and noisy.
The GT 420 is currently a bit hard to find (the 430 seems commonly
available), but I'd keep an eye out for it over the GT 220 as they
seem to be launching at a similar price.
