I am attaching the script I use.

Yes.

I know divx4 is obsolete. I was just testing. The only codec I managed to
record from TV on the fly was LAVC.  Without  pass=1 it xvid does not work
at all. After one minute, the recording is stopped (I do not know why). With
pass = 1, at leat it goes ahead, but gives me a lot of buffers overflow
(same thing with divx).

Is it possible to record on the fly with xvid?
