Thanks for the tips thus far folks. I have semi-fixed the problem. I uninstalled all my backing up software and reinstalled just 1 program (now up to 2): dvdxcopy, dvd decrytper. So far I have had zero coasters and have used 1x, 2X, 2.4X, and 4X media. I still prefer to use my original backup scheme: decrypter->dvd2one->copytodvd. However, I need some time to try this out again. Will let you know as soon as I can get it to work.
Forgot to mention that I used -r and +r media and both worked.
