I've downloaded a lot of music videos.
Some play on Banshee...
None of them play on Movie Player... --> The Default Player ---> doesn't even play the sound!
others play on Gnome Mplayer... Sometimes I get sound and no picture, and other times I get picture and no sounds.
They seem to all play on VLC..
1. Why all the Media players?
2. How do I make VLC my default media player
