Cassette Deck Popping...???

OK this is getting a little frustrating now. When I play a tape in one side it plays fine, but when I play it in the otherside i hears clicks/pops every so often. I posted on usenet (what a joke that was) and was told to demagnatize the heads (which i did to no avail). I tried cleaning the deck numerous times and still no luck. Any ideas? I really like this tape deck.

Thanks
James

...what brand/model?...

jimHJJ(...I recently had a similar problem with a new unit right out O' the box!!!...)

my pioneer is doing that same thing right now. but i havent had time to check it out. mine isnt every once in a while though its all the time like every second theres a pop sound.
