1. Ringtone, it depends upon what brand. Some brands allow you to do that. There's also some utilities you can get to help you. I answered a thread about that some time back. But you'd need to search the forum using the search button above. Also, you may find ready made ring-tones being shared. You just need to know how to find them.
2. Burn video to cd. If you have Nero, then see
Burning using Nero (click on link) for basics for burning VCD's. Also see RaaF's Sticky here
http://www.gnutellaforums.com/showth...threadid=38369 for audio burning.
