Actually, i'm not sure how I got it working, but at one point in time on my PC, I COULD paste clips to my hard drive. The ability to do this was only temporary, and it went away after a while, but i'm not sure why. I had a project I was working with in MSPaint, and I had a copy of part of it in the copy buffer. I went outside of paint, and hit ctrl+c over a file to move it, and I musta screwed up or some'n because when I pasted it (ctrl+v), it pasted the partial paint picture.
I managed to reproduce this with part of a notepad document as well. (By "reproduce", I mean it was accidental in that situation as well ).
But when I actually want to do it, I can't seem to...
Just thought I would throw that out there. There is no way that I know of to replicate this into videowave -- so just use the suggestion of removing all parts of the file you don't want, and then outputting the remainder as a video.
