I'm all AMD, as I want cool-n-quiet.  I may have to change that, but that's
a complete rebuild  of all of my frontends.  What would I need in socket AM2
to do it?

I have the 512mb "ASUS EN8400GS", not just any "8400gs".  Would it be a good
bet that it's the same exact one you have?

I was talking HD.  SD I'm currently using YADIF 2x, and would likely move
to  Advanced2X with VDAPU.

For PROGRESSIVE video does "onefield" lose half the resoolution?  if so,
why?  That doesn't seem to make any sense.   I understand that it will for
interlaced.  I could run BOB2x, but it seems silly to do so when the video
is already the perfect framerate, and only needs to be scaled DOWN (I run
720p for projector and 1360x768 for LCD tv).
