iTunes and Gapless CD Burning.. iTunes Problem or drive problem?

I've been trying without success to burn a gapless audio cd of a concert. I lost my original burned CD and am trying to burn another one, however this time around, im on a different Mac (before I was using a 1Ghz Emac G4 now Im using the 08 MacBook Pro w/superdrive)

Ive been reading about this issue which has lead me to no solutions. I have everything set correctly as I did before (set the album and tracks to Gapless and have the gap between tracks set to none when burning) but still get a "hiccup" between tracks.

One thing I did learn is that in order to burn a Gapless audio CD, the burning program and the drive need to support Disc At Once (DAO). I read that iTunes does not support this, but I know I was able to burn gapless successfully before. Here are the specs for my SuperDrive according to the system profiler..

And I just updated iTunes to the most recent version. Is there any way around the hiccups?? Any suggestions and possible solutions are welcome!
