Yeah, you know, I felt that I didn't have enough processor when I
got mine running last night too.  Watching live TV, with MPG4, bitrate 4000,

everything else default, I had some lost frames and general jerkyness.

And this on a Barton AMD 2500+, KT400 MB, 512MB PC3200 ram, etc.
PLENTY of horsepower.
