OK, tried ffmpeg instead, just as you listed above. But the audio now is
about 4 seconds lagging the video.

And I still get the  "flac @ 0xaafac30]output buffer too small" when running
mencoder, which I would like to know what it means, and can I fix it using
mencoder.

As for the editing application, it is obvious that it has serisous problems
handling different audio formats. I can load a flac audio only file into the
app (which is why I am trying to convert to flac), but the app gets very
confused with both a flac audio and any kind of video stream. If anyone has
suggestions for a good, simple editing app (trim, cut, convert) please let
me know. (I will probably switch back to LiVES, even though it is very much
overkill for my needs.

One other thing: if I go to using ffmpeg rather than mencoder, then how do I
capture from a tuner card? According to the manual, I need to set up the
v4l2 parameters in another running app, before starting up the ffmpeg
capture. Not quite the most elegant solution I would hope for :-(.

Thanks, Carl, for the suggestion. I will RTFM some more and see if there is
something I can tweak to get the audio back in sync.
