Could be any number of things. Manufacturer of CD can be important (Sony, Verbatim, Kodak, Tesco etc. etc.) but also CD Type. Have you tried Audio specific CDs? Normal ones should work fine, but if your player isnt recognising normal CDs, it might have more luck with Audio ones. Could even be the program used to burn the CDs. CD players vary so what works on one, might not on another.

But so much for BMW over-engineering lol...

Ellie, you need to 'Close the Session'. Effectively, you are then creating an index for the CD player to hunt out each track. WIthout closing the session, the CD can see there is a CD, however, it doesn't know at which points to find the music data. Computers can read them because they use a different system which doesn't discriminate which data is which, so it doesn't matter if you don't close the session.

MP3s are considered standard data however, not music data. However, the MP3 decoders are added to the standard CD player in order to read standard data, thus pick up on MP3 files, perhaps even AVI and JPG (your DVD player may do these tricks)- In this case, you wouldn't need to close the session.

There maybe a tick box somewhere in the software you are using. Remember, once the CD session is closed, no more music data can be added.

One other point, some CD players may not spot some CD's because of their construction or maynot be able to easily read them, however most moder players don't have a problem. Always use good quality discs and steer clear of OEM types (unbalanced, untested).
