I just upgraded to Ubuntu 7.04 and I have a few questions.

How do I stop Beryl from loading on login? The only reason I had it was to have the cube desktop, but the new Ubuntu has that natively and I want to delete it. I can remove it from the Add/Remove apps program, but I'm sure if I do that without removing the reference in the auto execute file it will cause problems.

There are tons of music players to choose from. Which one acts the most like iTunes, both in functionality and interface. iTunes is what I'm familiar with, but I can learn a new GUI, I mainly want a program that will play ANYTHING. Wav, Mp3, AAC...

What is the best movie player? Which one has codecs for almost everything. Media seems to be lacking in Linux. I heard that there is a player that will automatically download the correct codec if it doesn't have it, which one is that?
