Unfortunately, Verbatim +R DL blanks that are made in Singapore are the only DL media that's worth using.
I am unfamiliar with the dvd-rom setting. Can you enlighten me a bit on why or what this does, and how changing this setting improves copying?
It does not improve copying. Changing the booktype to "dvd-rom" improves the likelyhood the media will be played back in more standalone players. Doing this step affects playback only. But this step is important because Slysoft software does not change booktypes.
I don't have a copy of CloneCD, just CloneDVD2. I went through so much money trying to find something that would let me back up my dvds, before I finally arrived here and got the info I needed. Or at least enough to let me do what I needed to. I have only had one or two failures with AnyDVD in general. I have noticed the break problem, but since I see the pauses occasionally in my regular disks, I guess I have learned to accept them in my back ups with less problem, even though it is an alteration of the movie as released.
Your problem is you need to use Verbatim +R DL media. Clonedvd2 will not retain the original layer break position (nor will Shrink, Recode, and other transcoder based applications), but it should still work reasonably well with Verbatim +R DL media (that's made in Singapore). Anything else is simply not worth using, imo.
If you really want to make 1:1 copies of movies using +R DL media, then you should be taking a look at Clonecd, if you also use Anydvd.
I am more concerned about unreadable disks that negate the whole process, or in this case, unwriteable files. Which brings me to a point. As I was writing another movie, I got a media failure error message during the process. This is a different message than the redundancy error message I started this thread with. The new error message suggested simply changing the media I was writing and trying again. Which I did and everything was fine. Exactly as I expected if there was a "write to" disk problem.
Again, the problem is your choice of blank media. When you use Verbatim + R DL media, you won't come across as many bad blanks (like the ones you've encountered). The reason there is a "write to disk problem" is because you had a bad blank (this occurs more often when you use non-Verbatim +R DL media). At some point you have to ask yourself if using inferior quality blanks is really worth it. Burns produced on Verbatim +R DL media are better; consequently, those discs will play over a longer period of time. Verbatim +R DL media also tends to be constructed better than the cheaper stuff.
