Hi Sleepless,
I think this matter can now be resolved.
In Nero express at the top (I must be really stupid) as you know you can burn in different formats, and I think the first one that plays O.K. was done in C.D. and the others in C.D./DVD, that is why they are not playing in my car but do in my DVD player. Just tried another one in C.D and its fine when in the car player. Must now go out and buy some more C.Ds.

Still would like to know how i managed to be successful last year burnig an audio c.d. from wmp.. Thanks for all your help, could'nt have done it with out you... Roger..........
