leftyman--I don't have that cd, but I'm guessing it has the standard 2 seconds between each track. With Nero, after you've setup your compile, you can highlight all the tracks you are going to burn, right click, and cut down the silence between tracks. Some people like to have 0 silence. This should give you enough space to squoze it on an 80 min.
Ooops....I believe you have to leave 2 seconds selected for the first track only. Can't remember why. It's standard or something.
Sometimes, I want to sqouze just one more song on, and will select something like .5 sec between tracks. I believe it defaults it down to .33.
Ooops....I don't believe you can just use "copy cd" function in Nero for this. You'll actually have to select each track, and burn it as if it were a compilation.
Also, the table that rlism linked.
And, you can use CDRidentifier to see how many minutes your specific 80 minute cd will burn, without "overburning".
