How can i edit dvr-ms files and how can i convert them to mpeg format?

I want to be able to get rid of the commercials on dvr-ms files from movies that i record? I’m not really really sure what type of prog. to use.? and how to go about it?

Secondly how can i put dvr-ms files on a dvd to play in a dvd player? I can get it on a dvd but it will only play on a computer with the windows media edition. It is a pain in the butt.

If you can answer either of these write back please. Thanks everyone
