I don't have the links handy. I heard there was an issue with X 10.1 reading the VCD format. You might try FreeVCD or QT from Classic (is that possible?). The other alternative would be to just go to OS 9, copy the relevent files to your HD then you can view them from X as often as you like. I haven't tried reading a VCD in X but I have viewed the files copied to my HD with QT in X.
Someone has an app out that will extract the video files to your HD so you can burn them to a CDR. You still need to boot OS 9. It may be on version tracker.
If you can't copy the file in OS 9 first open it in QT then save it in QT to your HD. Make sure to click (unclick? sorry I can't recall) the box for saving with dependencies when you save the file. You want to save the whole thing as a self contained movie, not just a pointer to the movie.
