DVD backup Issues

[eagledefender]

I am trying to make some DVD movie backups and I am having issues. I am useing DVD Shrink 3.1 and CloneDVD2. I have also tried using DVD Decrypter3.1.7 and Nero 6. I have been able to make a copy of a movie on a DVD+RW, but it will only play in my DVD+/-RW Drive. I have tried to use DVD-R's and the programs spit the disk back out.

I want to be able to make backups that will play in my DVD player and other DVD drives/players.

I have a TDK 440N DVD+/-RW burner and my DVD player is a Panasonic DVD-CP67.

Can anyone help me figure out what is my problem and how to fix it? Is it Certain settings or the correct software configuation?

thanks
