http://www.riverpast.com is a great site for conversion sortware and most things to do with video. I've looked at most of the software and I must say that Sansa video 2.4.1 is a worthwhile software for those hundreds of people who own a Sansa and can't work the built in software. I think I'd be great idea to get some of their software. Thanks for listening.
