I have a 2004 truck with a DVD player in it. The player in my truck will not play any of my backup disk of movies I made. Now these movies do work in all 3 different player that I have. But all of my original will work in the truck's factory DVD player. I've been using DVD-R by Taiyo Yuden(they're not the fake ones). I even tried some Ritek and had the same problems. So today, I read something about bitsetting using DVD+R and it worked(using Nero) in the truck player. Could someone tell me if, all originals are DVD-ROMS. If I will be losing quality by changing my DVD-R's to DVD+R(DVD-rom setting)? Until today I thought that all recorders was compatible to DVD-R. I like using the -R, is there anyway to make the -R work in the older recorder?
