[theora] ffmpeg2theora and VOB files

This appears to be the problem:

FFmpeg does not list this as a supported video format:
http://ffmpeg.org/general.html.

Perhaps this means you'll need to encode the audio and video separately...

Since you have the video plugins, perhaps you could encode the video
by using something like Thoggen? Thoggen uses the GStreamer multimedia
framework, and so should pick up on your plugins and give you access
to the video.

I thought GStreamer supported AC3 but since you say it doesn't,
perhaps you could get the audio by running it through ffmpeg2theora.

Once you have the two separte files (one for audio, another for
video), it should be possible to use something like oggzmerge to get
them into a single file.
