Yes, as a matter of fact, I can. I made the beginner’s mistake of using stick-on labels (CD Stomper) on a dozen or so I burned early on. They worked fine at first, but then started to pixellate and hang near the end of the film. I had to transfer them to new discs, and in every case the 411S read and copied them perfectly.
One of them was from a really poor source disc, a rental that looked like somebody had scrubbed it with steel wool. It took more than an hour to rip it the first time because DVD Decrypter kept retrying errors.
Surprisingly, the copy of the copy went without a hitch.
I’m not a fanboy, and I’d tell you if I had a problem. Knock on wood, I never have. It worked perfectly with +R before the conversion, and perfectly with -R after.
I liked mine so much I bought one for my son, and he doesn’t have any problems either.
