I use winamp & kmplayer
I have to admit I use iTunes for playing music files (very convenient for me because I own an iPod)...too lazy to try other media players but I know there are better ones out there!
I rarely watch videos on my computer but if ever I do, WMP for me.
Itunes for sure
I use KMplayer and Windows media player
winamp for music and vlc for movies.
i use winamp and wmp.
I don't listen to music much on my computer (I normally just turn my iPod on since all my music is on there) but when I do I just use WMP. For videos I use VLC

iTunes, but I don't really like it, since it doesn't support a whole bunch of formats. I really hope for Vox.app to make its way to a really cool media player.
