Your supposed to use one brand of tape and stick with it haha. Thats why you having problems. Different tapes use different lubrications, so when you switch tapes you mix them up and get dirty heads. If i were you, i would get a head cleaner, run it, and just get some panasonic tapes like these http://www.amazon.com/Panasonic-MiniDV-Tapes-Pack-5/dp/B00007FWP2 . Once you run a head cleaner, only buy one brand of tape, if you have to switch for some reason, run the cleaner before you start using the new brand.mat said:i have used a bunch of different ones and I have had problems with some
