After reading these forums, I have used the DVD shrink, and NERO software under many methods on my new DVD recorder, and using both -R and +R disks to get one of my backups to work on my regular Toshiba DVD player that's connected to my TV. The Backups work fine on my PC, but not on the Toshiba. One person told me to create a new directory called AUDIO_TS, and put all other files in a VIDEO_TS directory. This allowd the new backups to work on my PC, ... but not on the TV. I get a "DISC ERROR" when I insert it into my TV DVD player. NERO has many options for backing up DVD's, (ISO, ISO/UDF, UDF ... ) how do I know which one to use??? Thanks for any help you can provide.
