If you wanna watch dvds go ahead and grab those as well, "sudo apt-get install libdvdcss2''
You may have to enable a different repo, so if that command doesn't find it try enabling universe, or multiverse I can't remember which.
Ubuntu has very good documentation, so check the wiki and forums, as any question you have in the future will most likely be answered there.
I cannot get WMAs to play, but I did get a DVD to play- although there were visual artifacts. I'll try what you recommended and see if that solves the issue.
