How come?  You want to use v4l2 anyway.  Much better a/v syncing
results.

Well, MPEG1 is definately not as good at compression as divx/mpeg4.

Lemme see what my record (in cvs) script barfs out...

$ mp1e -vv -n 39200 -s 640x480 -b 5000 -f 29.97 -a 0 -B 128 -p /dev/dsp1 -S=
 32 -x /dont/set/mixer> "/video/test.mpeg"

Yes.  I record with mp1e at 5Mb/s bitrate and usually don't do
anything with the resulting ~1.1GB/hr file other than watch it and
delete it but occaisonally (too occaisonally :-) I run out of space
and use mencoder to re-encode to mpeg4 at at bitrate of 1.25Mb/s.

But I am a stickler for picture quality.  I don't want to see
pixelization.  :-)
