knight rider online

I want to mash up some Knight Rider episodes to make something new out of it. I picked up Sony vegas movie maker 9 and I can't seeem to bring the material up when it is on my hard drive.

IS this a copywrite issue? I know you guys do it and put them on youtube.

Trying to figure out how to do it.

It's possible that the format for the video is not supported by the program.

How did you get the files onto your hard drive and what format are they in? I use something like this to record from my DVD player or VCR directly into my editing program.
