What's the file name?
PORNOGRAPHY_I_SHOULDN'T_WATCH.avi?
I'm only joking!!! hahah.
I couldn't get totem to work either.
So I downloaded mplayer.
Works sleekly - I can play songs without the actual player appearing.
So, as root:
yum install mplayer
and start pumping those music. You might want to download the graphical mplayer because when you watch movies with Mplayer, the colour might go all funny. With the graphical Mplayer, you can fix it so the colours show properly.
Good luck.
Chuong.
