Hi, I have the following problem. I burned with an MP3 CD and wanted to hear it in the car. The car radio (Kenwood) can read both MP3 and WMA. With two other MP3 CD ́s everything works as it should. Just this one CD jerks and hangs up sometimes. Can always happen that the burner has built shit. I just wanted to try this and put the CD into the PC drive and listen again. Now it runs perfectly. So why is it that the CD in the car radio ruc other CD ́s work as I said. I haven ́t heard any more MP3 CD in the car for a long time, but it can ́t be because the lens and the rest of the radio doesn ́t really matter if an MP3 or a normal CD is played. Hope you understood what it is all about. ^^ mfg
