Hmm... kino was (at one point anyway), playing back on a p3 800 without
dropping (assuming you weren't compiling the kernel or doing something
stoopid in the background). Don't think that's still the case as we have
more parallel stuff going on with playback. Good XVideo rendering is the
real key to this (the p3 800 had a lowly i810 installed btw).

Personally, I playback DV on a TV connected to my cam. Perfect playback
the way it's intended (resplendent with correct interlace handling and
proper colour handling... also ticks away nicely with very low cpu
usage). The canopus can be controlled to switch between analogue input
and dv playback too (just using dvcont and dvonnect for send/receive).
The dv1394 stuff of the newer kernels is pretty simple to use too.

Kino 0.6.3 has an option for previewing via dv1394 while you're working
in the editor - 's very nice :-)

Cheers,

Charlie
