I have been doing alot of transferring of my tapes to my PC the last few weeks, now there seems to be some problems with my camcorder. When I try to play the tape back, the picture has large macroblock type lines across the picture and the timecode is progressing at probably twice the speed. I had this problem arise on a few other tapes earlier on, and I would simply rewind then fastforward them to get it to stop. A few times inserting a different tape and playing that one seemed to work. Now, ALL my tapes seem to have this problem and no shuttling from end to start is helping. Could it simply be my heads are dirty, and if so, how do I go about cleaning them. I don't think I have seen a Head Cleaner kit for mini dv.

TIA
