Tapes won't play and won't retract when ejecting

This is the most common VCR problem of all time. The piece call the idler tire is worn down and needs replacing. This is the little wheel in the mechanism between the 2 reels that flips back and forth depending on which direction you've told it to go. It has a rubber tire around it to allow some slippage so that the take up reel can go whatever speed it needs to as it accumulates more and more tape on it as it goes through your movie. Sometimes this tire is very difficult to get at so it isn't something you should try to do yourself unless very mechanicly inclined. Replace the rest of the rubber belts while you're at it.
Hope Ya Fix it!
