If you have a DVD rom drive on your PC, you can play a game where you redub the dialog. I believe that it's called revoice studio. If you end up with the DVD and have problems with the program, drop me a PM. It turns out that our PC had the problem and I managed to find a workaround that the software publisher is now using. They even offered me a job as a beta tester.
IMHO - I would always go for the DVD over VHS tape.
