It's my understanding that you can't copy a copy made w/ dvd express because that program puts a watermark on the copy.
Try using any disc copy program. As in Nero or Recordnow Max. The only time X copy discs can't be re-copied is if you try to use X copy again. The disc is not encrypted so any other program should work. I had no problems back when I used X copy Express. Jerry
Only reason I use DVD X Copy is because I bought the damn thing , I tried to use DVD Shrink and decrypter ended up with two Coasters.
have you got nero 6 ? iff not download the trial im sure theres a link at this site , its for 30 days , so give it a try . it will copy dvds done with xpress no probs , as i have used it and it works . just give it a try theres nothing to lose .
