I do not even know what over-burning is...
There seem to be two uses of the term "overburning", one technically correct, the other not.
Technical overburning is getting more burned onto a CD than it is actually designed to hold. So, say if you have an 80 minute disc but your playlist has 82 minutes of music {say, the last song is 5 minutes}, by doing this thing called overburning, basically you fit all 82 minutes on the disc because the additional few minutes are burned to an area no music should go

.
Officially.
Depending on the CD player you then use, you may get to hear and play all 82 minutes on the disc or it may start farting about around the 79 minute mark, not playing and whatnot.
Whatnot could be anything from strange whirring noises to jumping back to the start of the last, second last or even opening track.
But there's also the incorrect overburning that I've discovered. It's not really overburning at all but the two programmes I'm using {Burn4free and InfraRecorder} call it that and treat it so.
What happens there is that many burners can't or won't go over the specified 80 minute maximum, so if you stick a 90 minute, 800 MB disc in, you'll only get at most 79 mins 56 secs or whatever an 80 minute CD is in actual real time. You'll be notified that you can't fit everything on the disc and would you like to burn onto multiple discs ?

At which point on those two programmes I mentioned, you get the option to 'overburn'. Of course, it's not really overburning because if your playlist is within the 90 minute time span, the CD should be able to accomodate it. But some
burners won't. So they say they're overburning, even though they're not fitting more on than there should be on a 90 minute CD. They work their magic and behold ! A playable audio CD of up to 90 minutes {800 MB} on a disc that says 90 minutes on the box but which the computer tells you only has 702 MB.......
The interesting thing about 90 minute discs is that some CD players
simply will not play the entirety of the disc ! I have 4 players at home. My 1998 Phillips will play the start of the song that goes over the 80 minute mark but a couple of minutes over the 80 minutes it just stops and whirrs. Any song that starts after 80 minutes won't even begin though it will register.
My 2000 Phillips will play the entire 90 minutes to the end but if you want to play the last song or maybe last couple of songs, you can't just skip to it and have it play, you have to play first the last good song that can be skipped to. Then it will carry on to the ones you want to hear at the end.
My shitty Sony radio/cassette/CD that could barely be given away plays every track and you can play from any position. My standalone Sony CD player does likewise. As does the computer drive.
Go figure !
The reason I want a burner programme with CD text is for the day when tape is no more and I have to switch to some iPod~ish type gig. When I burn via iTunes, the track names are written and remain on anything 80 minutes and below. On the freebies I have, they burn perfectly excellently but there's no text. In the event that something should ever happen to my insert{s}, the CD text would save me mucho hassle.
There you go Chili, a shaggy dog story for your travels !
