Hi.. anybody experience this? Every once in awhile the CD player won't take the CD. Sometimes it's a CD-R sometimes it's a store bought CD. The unit will pull in the CD.. but will never play the disc. I can hear the rollers spinning (like it doesn't see the CD) and after like 20 seconds it will spit out the disc. If I keep trying.. eventually it will take it and start playing. Is that something that I can have fixed under warranty? Or do I just need to clean the CD player somehow? I have a 2004 (non JBL) with about 30k on it. thanks so much, Peter B
