You want a Time Base Corrector or TBC. This will also help stabilise the picture if the tapes are old. The best one to get is the Datavideo TBC 1000 which sells for around $290 online. You can get cheaper things but they won't give as good results. I would suggest starting at www.digitalFAQ.com. Then go to www.videohelp.com/www.doom9.org forums for more specific answers. Other than that, you could always wait for MeBeJedi's and Zion's LD transfers which will be better quality anyway.
