Do the problematic CDs you have burned play properly in other CD players?
Check it and see. Some very-slightly older CD players just don't handle
CD-R media very well. It's quite possible that you're doing nothing wrong
at all. CD players which have problems with CD-R media may handle some
CD-R brands better than others though- try burning to a different brand of
CD-R, and/or at a slower speed.

I can also agree that CD players (especially 'in car') are very variable at how they cope with CD-R's (ones you record yourself) and the type you use will seriosuly impact how well the player copes. I assume using Nero, you have started with .wav files in which case it should record OK, but double check the new CD will play on a recent CD player (portable or walkman or something). If it well then try recording using a top quality branded CD, preferably 'gold' standard. In my extensive experience, if you can still get hold of gold CD-r'S (I thnik most stopped making them because they are genuinly more costly to produce) try them. they do work much better.
