I have backed up several movies using DVD Decrypter, DVD2One and Nero. They all seem to play well enough on my 2 year old Sony DVD Player. I have had a few that seemed to "skip" or "hang." However, I recently tried to play several of my backups while on vacation and could not get any of them to play without problems. The player was a Panasonic. Each time I tried to play a backup, I would get a "Format Error" message or it would just "hang" and never play. I was about to buy a new progressive scan DVD player and now I am worried and want to be sure that the new player will play my backups. What DVD players do you reccomend that you know play these backups without problem? Does this have something to do with the "error correction" ability I see listed in the specs of some DVD players?
