Figure around a 2Ghz p4/xp for comfortable playback (without deinterlacing, of
course) of 1080i at full resolution -- I was seeing around 75-85% cpu or so
with my 1800+ when I was playing around with some hdtv demo clips last month
when I did the mpeg decoding optimizations.. Found a deficiency in the
nvidia Xv driver, while I was at it, in that X takes _lot_ of cpu to
downscale video from that resolution to 800x600 or 640x480. Displaying at
1920x1080 was fine, though =)
If someone wanted to hook up the (very preliminary) XvMC support code that's
in libavcodec to mythtv, that'd help out playback time on supported cards.
It'd require a bit of work, though.
