Hi, Have a really wierd issue with some mp3's that I have got. I burn them on to a CD to play in my car and I can play quite a few of them but there are some that show us as 'unsupported' but play just fine on my creative zen and on winamp! Am really baffled about this, have tried different media but no luck. Is it possible that these mp3'z have been encoded by a software that my alpine mp3 player cannot read? I did not think this was possible?
