        What's the usage like with 480x480?  I think your system
should be able to handle that.  I have two Bt878 cards on an
Athlon XP 2500+ (1.83GHz), nForce2 system capturing 480x480 MPEG4,
2000 bitrate (1500 eff.), 4MV and HQ disabled, adjust and quickdnr
filters enabled.  CPU usage is 60-75% when recording two programs and
playing one more at the same time.  I don't transcode.
