I authored a dvd9 project in Maestro, then I burned it using DVDDecryptor. The project is about 7.31 gigs. It seemed to burn fine but somehow failed during the "verify" process. I played the disc using WinDVD 5 player on my computer and everything played beautifully. However, when I play the disc on a Sony set top DVD player, it failed during the last part of the last chapter (10 chapters in total). Can someone advise me if this is a player problem or the burning process was bad? The disc played fine on my computer though.
