When you copy the files are from the original make, start Anydvd, make sure ClonedDVD’s “delete temporary files after writing” is not checked. Also make sure that in AnyDVD the Use CSS key Archive box is not checked.
Once you have made your first copy, close AnyDVD, then in CloneDVD select the third button, “write existing data”, and make your next copy. Once complete, if you want another copy don’t exit CloneDVD, but rather hit the back button and copy the files again to a new DVD.
I would not suggest making a copy of a copy if at all possible, from what I’ve read, that copy will be degraded somewhat, and if you use the copy of a copy one as your source, that DVD will be degraded even farther. I personally can’t verify this since I’ve never made a copy of a copy, I will use the original as the source.
P.S. Make sure you have sufficient hard drive space to copy the files to, if you have many movies saved in the temp folder, perhaps try deleing some.
Another thing I always do before burning is defragment my drive where the movie will be stored, this is important to avoid errors.
If the above doesn’t solve your problem and you believe it’s some sort of memory issue you can always reboot after making the first copy and then try making a second by the method described.
And of course use only quality media to rule out it being a media issue.
P.S. Be sure to defragment your drive before burning, this will avoid problems.
Anothe thing make sure there is sufficient hard drive space on drive you are copying the files to.
