Not a clue.. They disable a lot of dvd and video tools in ubuntu because of the stupid USA restrictions regarding dvd's.. Try enabling the universe and multiverse repositories.. or better still get familiar with the terminal.. you will only benefit from the experience..
I'm running source built software (from the debian repositories) on FreeBSD, so what the situation with ubuntu packages is I honestly can't say.
Find your /etc/apt/sources.list file and add this line
save and then apt-get update.. this adds lots of video and dvd capabilities. (check out the site too.. they have lots of really good info about linux and multimedia there)
another pretty idiot proof converter is DeVeDe. Very similar setup as ConvertX on windows, conversion time depends on the speed of your machine. (just remember, garbage in garbage out)
varnull, I agree completely about the US restrictions issues. I would say a few strong words about it, but that would be digressing. In any case, would the packages in debian-multimedia be compatible with ubuntu? I am running gutsy, so I am curious about how it relates to the debian distros.
Ubuntu is a debian based distro so most deb packages should run without too much trouble. I cannot say for sure 100% as I havn't used Ubuntu in at least 6 months and it is surprising what you forget in that time.
All you really need to know is which debian release your ubuntu mirrors.. It is usually 1 release upstream from debian.. so ubuntu stable will be debian testing..
Most of the debs in the debian-multimedia repos are "debian-all" so compiled semi release independent (they will work on arch and dreamlinux as well)
