But keep in mind this, the Ipod Video's capabilites, mainly MPEG4 at 2.5mbps. This is like 18-19 MB pr. minute, if I'm doing the math right. (And like 5.7MB for H264) Just keep it less than that! :-)

Is the quality bad at 20KB/sec 3ivx? I think it looks pretty good, and
it's certainly great to have the videos load 4 times as fast.
