I have a DVD recorder and have recorded some football games from my TV. I'd like to edit out the commercials and such. Does anyone know how to go about doing that?

Also I've taken some small movies clips with my digital camera and I'd like to cut some of the scenes out to clean them up so to speak. What do I need to accomplish that?

Thanks for the help, by the way I'm fairly new to all of this so please be patient.
