Why does it have to be realtime? You will get a better quality encoding
if you allow it to run in the background.

I use dvgrab to capture the raw video (in realtime) from a DV1394
source (camcorder) and save it to disk. dvgrab writes one file per
recording scene and each filename is the timestamp, so it's quite
easy to separate different recording sessions.

A 60-minute tape occupies about 12 gigs of disk space.

I split it up into one directory per "movie" and use a tool to
concatenate all the scenes into one big AVI.

I then use mencoder (see http://www.mplayerhq.hu/) to encode
the concatenated scenes, non-realtime, into 3 or 4 DivX files
of varying bitrates.

Nick.
