Hopefully the missing data should be there, either wrapped, or off the edge
of the page.
I'll also put up a link to a clean copy tonight.
The script detects if there is a ffmpeg compatible audio stream, and skips
the VLC part.
I also roughly detect the resolution and set the aspect ratio so things look
normal on the final output files.

I'll check it with a file from TV3 with AC3 and try that tonight also.
