Three days ago I backed up a new movie I purchased - no problem. Last night I tried to back up another new movie and the burn failed. If I check the status of the disc drives, only the disc drive with the movie shows up. My other two drives either have the message "no disc detected" even if there is indeed a blank disc in them, or I get the message "AnyDVD cannot activate the disc drive" (or something similar to that terminology). Any one have any idea why it would work one day and not the other? I'm running the latest version of AnyDVD (I've removed and reinstalled it). I've got XP. I don't think it has anything to do with the time change as I have successfully burned another disc since. And, I have tried other movies to no avail. You know, insanity is when you try the same thing over and over expecting different results. Apparently, that doesn't apply to computers.
