Actually it is remarkably good. The Dual Celeron shows 98% idle (on top) for
both CPU's while capturing @ 720 x 480. This may change though when I switch
to using a big IDE drive. Right now it is using a fairly fast, and small
:( , SCSI drive.

The frontend is a 1.3G AMD and it uses ~40% to playback the stream.

Very cool. I can hardly wait for the ivtv driver to become multi card
friendly so I can put another PVR-250 in to the dual system to record while
watching live-TV.

I'll keep an eye on it and see if it reoccurs.
