I have recorded all of my VHS tapes to my DVD player. Played movies from my camcorder through the VCR to TV then recorded tapes to my DVD player. Everything worked fine and I can play back DVD’s, only problem is I can only play it on the DVD player that I recorded them on. All other DVD players, computers, xbox say the DVD is unreadable. Is there an easy fix for this, or do I have to redo everything through my imac using imovie and idvd? (used DVD+R)

You need to look in the manual for your dvd recorder and find out how to finalize the dics that you have burned. This should be the easiest solution.
