Which is the best multimedia enabled linux distribution(non-live)?
Does it have DVD Authoring software? Does it have mp3 ripper? Does it have a good image editor?
every linux distro has DVD authoring software like K3B. Gimp is a good image editor which again is present in almost all distros. Many distros do not provide support for mp3s while installation. But you can install 3rd party appl. like Mplayer.
I would suggest you to use either Fedora Core 5 or Ubuntu (Dapper Drake)
