I'm trying to backup a DVD onto a DVD-R and I keep getting a failure to write, bad media message. I'm running CloneDVD 220.127.116.11 and using a NEC DVD+-RW ND-6650A to burn the discs. I can write a CD fine, but since the upgrade to the new CloneDVD version I'm having problems. Any suggestions? On a side note, I've been writing to DVD+R prior to this and everything has been working fine. I'm assuming DVD-R should work just as well. Is that a wrong assumption?
