I have a plextor unit that allows me to take VHS, cassettes, etc and run them through that directly into the computer, where I can save it and also edit and put music, subtitles, that type of thing on it and make DVD or CDVDS out of them. They aren't very expensive. Might be worth getting one for the Batfish and converting all the old ones before they go bad. I think they have one that retails for around $70.
