converting a vob, video is double speed and sound is distorted

[Brazen]

I've tried several videos - Aliens, Fiddler On The Roof, Gladiator. This is specifically on Ubuntu 10.04 with only packages from the official repos and libdvdcss from medibuntu, but I've had the exact same issue on older versions of Ubuntu.

I extract the vob from the dvd using 'vobcopy -l'. I can play the vob and it looks great in vlc. I then try converting the vob with 'ffmpeg2theora --audiostream 1 file.vob'. The resulting file, the video plays through at double speed and the audio plays at normal speed but is very distorted. If I add the --sync option, the video plays normal and audio plays normal speed but the audio is distorted even worse.

I don't understand why it won't produce a good copy for me, I hear lots of people convert vobs with ffmpeg2theora just fine. Also, Thoggen does works fine, and produces a good ogv file, but I would prefer a commandline program.

please try a build from http://firefogg.org/nightly/ or the latest release from http://v2v.cc/~j/ffmpeg2theora/
the version in ubuntu is outdated and might have the problems you desribe.

downloading and using the latest ffmpeg2theora from the website seems to work better. The sound is fine now, but the video does not turn out. Using default settings, only about the first 1/3rd of the video is rendered and then it's blank after that.

could you try again with current builds from http://firefogg.org/nightly/ and provide a link to sample if it still fails.
