The same problem on Panasonic NV GS 11 Mini DV

I have the same problem with the horizontal lines during playback...I have waranty just a month and it's really stressing. I gave the camera to a tehnician to repair, twice!!!, but the problem seems to persist. In my opinion seems to be a software problem, which is common on multiple Panasanic Mini DV camcorders...Sometimes the stripes dissapears when I choose the recording mode, but is not for sure 100%...It's not a problem about the cleaning head, it's a main electronic circuitry problem. If it happened again I want to go straight to the Panasonic office...
