Hi, I have 2 Liteon burnders on my pc. I use 1Clickdvdpro. It has always burned a great copy. Very recently I noticed that with most burned dvds 1Clickdvdpro is the only software that can read burned copies. My pc also has shrink dvd and Windvd. Neither of these can read the copied dvds. I like to reauthor dvds (music) and I'm at a loss to understand what's going on. Yet, the copied dvds seem to play okay in my stand alone dvd player. Can anybody help sothat shrinkdvd can again read these burned dvds? Thanks.
