It looks something goes wrong with ffmpeg two pass initialization:

I just tried to to a ffmpeg/mpeg4 2pass transcoding myself and got the 
same error message! I upgraded my transcode/libavcodec installation, but
that didn't help. Looks like a serious problem with ffmpeg, which isn't
able to read or find it's own divx4.log file.

I googled for this issue and found this posting:

  http://article.gmane.org/gmane.comp.video.mencoder.user/3612

So it looks like a known problem out of scope of transcode and dvd::rip.

For know you should use xvid for your transcodings.

@Christian Marillat: I used your transcode and libavcodec* i386 Debian 
sid packages from today. Are you aware of this issue?
