Thanks for your answer.

That's right. But somehow -mc 0 worked with the older version of
mencoder (without mc it was out of sync as well).

OK, it gets better, but it still isn't correctly synchronised. The audio
is about 0.5 seconds behind the video, no matter if i use -mc 1 (or
higher) or no -mc at all. It seems to me as if some frames at the
beginning are discarded. (But the -noskip option doesn't work at all,
this makes the video about 10 seconds to short).
Yes, i know, i could insert a negative audio delay. But unfortunately
the delay isn't the same with all videos (and i have to convert
different videos automatically).
What i really would like to know: Why does it work with the older
mencoder version, but not with the newer one?

OK, now i don't rescale it at all. But that has nothing to do with my
