I can give a little info here: First of all, even though both a Computer CD (CD-ROM) and a CD Player play Audio CD's- there is one big difference. The CD-ROM standard uses 'error-correction', as indeed just One misread Bit would 'crash' the program/data. The CD-ROM in your PC has extra electronics/logic to prevent this. You can consider your CD ROM drive 'backward-compatible' with 'RedBook' or Audio CD which came first.
So, therefore, if 1 or 2 bits are misread while just playing back music, you may not even hear the difference.
Nsgarch - so my guess is that when you burn at faster speeds, you may lose more bits, and therefore lose some fidelity. On the Linn website (in their FAQ's when asked whether Linn players can play CD-R, etc.) they talk about the loss of bits when burning a CD-R, but when I play a CD-R on my Linn Classik, I can't hear any 'loss' of fidelity.
Hope this helps.
