Did a little homework... Bought some Sony(+R) disks and created the same slide show. Viewed it on DVD player (A) it stopped dead at 2:32 mins into the show!! Replayed it on my PC using NERO ShowTime. No problem... played fine. Then replayed the RW disk, which I had created the day before, and it also stopped at 2:32; this disk had been viewed on a different DVD player (B), the day it was created. But the RW disk did play fine on the PC. Finally played the TDK (-R) disk and it played fine on the PC; but stopped at 2:32 mins on the DVD player(A). I finally played all three on DVD player (B)... you guessed it, all played fine!!! The only info abt the DVD players is- (A) is a JVC DVD/SUPER VCD/VCD/CD Player, (B) is a SONY Video VDC DVD+RW/+R /-RW/-R Player. I don't remember which player I used when I created the 12 disks, I suspect it was (A)..... but none of them stopped at 2:32 mins!!! So how do I determine if the are good or bad??
