I use this card to produce MPEG's. That is, I take the video into
MJPEG (with one of the higher rate settings, from 7 to 20
megabits/sec) and compress it with an MPEG encoder to 600 to 2500
kilobits/sec. Note that MJPEG is an editable format and not really
targeted for network nor distribution format.

The only real problem here is that the windows drivers leak memory
like hell. Doing a 15 minute capture renders my 64 meg machine out of
memory.

So if anyone would be doing a capture utility for FreeBSD I'll
definetly switch over.

The card also does MPEG-1 and MJPEG hardware decode.
