[Cube Inmate]

I have some MPEG videos taken with my Sony handycam, and only have limited software capabilities to edit. I can clip segments from the various files and paste them together, but I want more... I want to separate the audio and video components, edit them separately, and then glue them back together so that, e.g., I can have a continuous audio track played while a number of shorter video cuts are played.

Does anybody know of good, free software that might help? Let me add that the "free" part of this is more important than the "good."

Thanks
