I recall a few threads on a couple of kjs that converted THEIR laserdiscs to computer a year or so ago. Do a search on the forum. (box on left)
I do think it was rather painstaking, so unless new technology has been introduced, it will be quite an undertaking.
Good Luck!
p.s. there is/was a fellow in the UK that sells his converted pio-lasers onto dvds (compressed) on ebay , i saw a awhile back. Match them with your originals and you won't have to convert yours, if the price is right. You'll save lots of time. -just an opinion.
