My setup is a Hauppauge Nexus-S with a Conax CAM.

And my recordings start with a 1e0 start code, which is video,
and probably not the start of a keyframe, since the output is
garbled at the start.

Strange tho, since my recording does not start with that header.

What is the startcode of that header (I'll test waiting for that)?

Hmm, it didn't do that when I wrote it, did you put that feature in
with your patch (which was the reason for putting in the wait stuff)?
