VDPAU deinterlacing is very impressive... it's by far the best one
available in mythtvl

The 8400gs can do VC-1 decoding ; a more powerful video card will not
do VC-1 with VDPAU. For some weird reasons, only their low-end card
can do VC-1 decoding.. If you don't care about VC-1 then yeah why
But my 9400GT (similar chip as on the 8400gs)
can do both advanced & temporal deinterlacing at 2X rate for a video up to 720P.
After than I use either temporal or advanced 1X ...
Mind you, I think the "advanced" deinterlacer in mythtv with vdpau
does a better job than Temporal...

It's the holy grail of deinterlacing :)
If you've been happy with Bob over the past 3 years, you're going to
be very surprised on how good it is... Or maybe, that you could
actually find Bob okay for so long is a worry :)

Why don't you wait and try before making a decision ?
and the 8400gs is rather cheap anyway..
This is the one I wanted to buy to replace my 9400GT (to get VC-1),
but instead I replaced the whole motherboard with the nvidia 9400 IGU
It does HDMI
