It's a bad idea to work with .VOB files directly anyway. Files
on a DVD are a more a kludge than an actual representation of a file
system - they do not correspond to the actual navigation structure,
long film streams are broken into multiple files, etc.etc.

The best workaround is to grab the audio/video stream from the DVD into
an MPEG-2 file, a process that involves no transcoding or quality loss.
The easiest way to do is with:
mplayer -dumpstream dvd://

The resulting file "stream.dump" is an MPEG-2 file, but Cinelerra
will have trouble recognizing the ac3 sound. One could use, for example,
mencoder to transcode it into uncompressed pcm while leaving the MPEG
video stream untouched:

mencoder -ovc copy -oac pcm stream.dump -of mpeg -o film.mpg stream.dump

film.mpg should be editable in cinelerra.
