I have a problem with my Panasonic AG-DVX100AP video camcorder. When I insert a previosulyrecorded mini-dv cassete tape into the camera correctly like I have alwaysdone, a strange sound is heard and a blinking red message appears thatstates, "Auto Off Cylinder Lock," or "Auto off S reel lock."It won't playback the tape. When I take itout the mini-dv casste of the camcorder, the tape is out of the cassete andappears creased and stripped. The previous day I had used the camcorder andthe tape without any problems. I took the tape out of the camcorder after Iused it also. I wish to recieve help about what the problem is, and what Ishould do. Any help would be great. Thanks.
