I never had much luck using a DVD plus +R disc. I have no problems using a DVD minus -R disc to create TV slide shows and making copys from the original. I may be wrong but I'm pretty sure that the Pro-Show program does something to the original creation and formats the DVD from plus to minus but when trying to copy the disc it confuses the program and won't copy correctly.
I now use only Sony or Taiyo Yuden minus - R DVD media and I just don't have any more problems with anything at all.
I also found that most all DVD TV players will play Minus -R media but only the latest players will play a Plus +R as well as a minus -R
