Everyone looking at the media and not looking at the deck. I had a pioneer and the head went out of alignment. it would also skip. the funny thing was, when cold it would skip more, when warm, it would play with very little skips.
I would take the deck back for replacement.
also, now, I have a cheapo deck(cant remember the name its so cheap) in my beater. It somethimes decides to skip the tracks at the end of the cd, and i just give the dashboard a good smack, and it plays fine again LOL. The last time i smacked the deck was several weeks back.
