In XP it took me 6 minutes to burn a disk at 16x speed using CloneDVD2. I just switched to Vista and now it takes about 2 hours to burn a disk at 16x speed. The dvd rips to the hd fine and the burned disks play ok. So it works but it's just taking way too long. I'm using a Plextor PX755SA with the latest 1.08 firmware. Any suggestions on what could be wrong? Thanks in advance.
