I normally fly United or AA which don't seem to mind CD players in the cabin.

This summer I am flying LAX->FRA->CPT on LH
on a C upgrade from United and they don't like CD players. Any thoughts on an acceptable alternative? I want to use a newer technology like Minidisc but can't be sure that will be allowed either. I talked to customer service at LH and all they said was that "CD players are not allowed". They can't
explain why they are banned.

I encountered the same problem 2 years on SAA
flying JFK->CPT. It really makes a 17 hour flight painful when you have 100 CDs you can't listen to. The rest of the entertainment selections in F were pretty pathetic.

Any explanations for foreign carriers to completely ban CD players?
