Hi Kurt,

Your CD burning software will alert you if you've gone too far. Depending on your software, your limit may be a second or two short of 80 full minutes. If your software or editor will burn it, you should be OK. If you are at all in doubt, just play the last track on a CD player and make sure it plays through to the end. If it does, you should be fine. 

Sound Forge still gives me a warning if I'm exceeding the old Red Book maximum of 74 minutes - I just tell it to go ahead, since I always use 80 minute CD-Rs. I don't even think you can buy 74 minute discs anymore.

Best,
Gary

I'm publishing an audio CD for distribution with our fall auction. It is 
right at 80 minutes long, less maybe a couple of seconds. Burned to 80 
minute CDs, am I asking for trouble? If so, is there anything I can do 
to mitigate the risks? Last resort is to cut material, but that would be 
tough to do....
