I concur it probably isn't fast enough currently.  My desktop X2
overclocked to 2.6 GHz can't quite handle the high quality, 720p, ESPN
clip I've seen, and that's running in an 800x600 window.  Scaling
1080i to full screen and deinterlacing would be even more taxing.
FWIW, my current main frontend, a non-overclocked X2 4200 at 2.2 GHz
can't even handle the half-rate sample clip.

Janne, do you have any more information on this?  There's a mention of
a 2007 project on
http://wiki.multimedia.cx/index.php?title=FFmpeg_Summer_Of_Code but I
don't see anything about the 2008 project on
http://wiki.multimedia.cx/index.php?title=FFmpeg_Summer_Of_Code_2008 .
I curious to know more about how the parallel decoding will work,
especially with Myth, and which is the better upgrade path -- a faster
dual-core or a (relatively) slower quad-core.
