I'm trying to burn a .img file to a DVD-R with DVD Decryptor and I keep getting the error message "Failed to send Cue Sheet". The files were authored using TMPGEnc DVD Author, and I've used this exact same set-up several times before with no problem.

The only thing I've changed to my system recently was a switch to a new video card, but I didn't change the capture drivers at all.

Anyone have any idea what the problem could be?
