PCLinuxOS! Everything Works!
One of the most biggest challenges with some Linux distributions is getting all the multimedia to work. It's a real disappointment to not have Quicktime movies or Flash video play from popular websites like Apple.com movie trailers or YouTube.com.
The really great thing about PCinuxOS is that everything works! All my multimedia (MP3s, Window Media files, AVIs , DVDs, OGGs, etc.) work right out of the box! If for some unknown reason, I can't get a specific media file to play, it's just a simple matter of downloading the correct codec or data file from the repository.
