I've been using Nero StartSmart Suite for a couple of years. I've burned hundreds of disks using Verbatim DVD+RW and Verbatim DVD+R Lightscribe Media with nary a problem.
Yesterday, I burned 4 movies with Nero version 6.6.1.15. I watched the first movie on my Magnavox DVD Recorder and it was flawless.

After I started Nero Recode last night, I chose"Burn Entire DVD to DVD" as always and then imported the DVD_VIDEO folder as always. I hit "Next" and then it quit, just like I closed it. I tried running it through it's shortcut, same thing. I uninstalled it using a registry cleaner and re-installed it. No solution. Rebooted and so forth. I've done everything I can think of but it still just quits on it's own after I hit Next. I have nothing running in the background and I ran Ad-Aware and Spybot to make sure there wasn't anything running that i didn't know about. I'm using Win XP SP2, I have a Pentium 4 2 Ghz, with 1 Gig of RAM. I have a bit more than 10 gigs free on my hard drive.
