I believe I have received the same error, but when burning a CD of MP3 files. It occurred when I accidentally changed a filename in its original folder, after creating the filelist in CDBurnerXP. The error appears, but no further burn progress occurs. The DVD drive light remains on, the Cancel button doesn't work, and even killing the processes using TaskManager doesn't release the drive. The only resolution is to re-start the computer. A screen shot is attached.
