[MPlayer-users] Playing large frame-size uncompressed sequences

Gurus, 

Very soon our laboratory will be acquiring several sequences
of progressive HDTV data. 10 second long sequences.

Each frame is 1920x1440.  The data will either be
in YUV 4:2:2,  YUV 4:2:0, or RGB format, progressive, 60 fps.

I can convert the individual frames to any uncompressed format that
Mencoder/Mplayer would like in order for Mencoder to generate me a
playable file.


My question is: will Mplayer be able to play this in "real time"
(i.e. 60 fps) out of memory?  I'm prepared to put the 4 or 5 GBytes of
Ram in the machine and get whatever video card is necessary.  Will a
dual 1.3 GHz Athlon (or similar) machine handle the needed data rates?
