It's sad how people encounter a problem and then go down the wrong path entirely trying to find a solution, straying further and further from the real issue.
This is what I see happening here.
Rex, here's the (very probable) cause why your cuesheet is rejected... One or more of the wav files must be shorter than 6 seconds in playing time (check them all in WinAMP or a wave editor)...if so, you need to append silence to bump up the playing time above 6 seconds for the offending wav file.
The CD-ROM spec calls for a CD audio track to be at least 6 seconds long, otherwise it is illegal. That's why your image won't burn.
Incidentally, what game is it anyway?
