I am just trying to answer the original question, and I skipped all the fights so if I am repeating someone, I am sorry.
A distro that works for multimedia?
I run Mepis 3.3.2 (debian-based, and it does work for all of my hardware) and got the new Repo sources from www.mepislovers.com
and I am just taking things from the Testing branch. Everything works for multimedia that I have tried, although I've not tried any television stuff. KDEtv might work there, no idea.
