Try a different vcr. I have a few tapes. They play like crap in one. (Especially if it's an emerson vcr. )
Plays great on the other 2 JVC & hiatchi
What could it hurt? LS , ducan, etc may be able do something with it. They have the hardware to clean that up. Switching cases wont do much good. Its on the tape...
what the hey. Whatever twirls your beanie
