1/ I used MTR to extract a VOB of a main feature from DVD
2/ I used ffmpegX to convert the VOB to XviD
3/ I'm trying to get the idx/sub subtitles out of the VOB with the tool in the Filters tab.
4/ The idx/sub sutitles seem to work okay, and complete...
...but I get an Applescript Out Of Memory error, while the eight-stripe spinning thingy stays on the ffmpegX window, but the output idx/sub files don't change filesize or change modification date after that.

Doesn't seem right.
