I recently played back a DVCam recorded tape in my Sony TRV25E not realising that it was a DVCam tape rather than a DV tape recording. However, I did learn that my camera appears to play back DVCam tapes ok. But soon after that my camera chewed up a tape and is now having problems playing any tape (dropout of sound/ pixellation of images). A head cleaning cassette hasn't cured the problem and I've had to take it in to a Sony agent for repair. Could my playing back of the DVCam tapes on the camera have caused a malfunction or is this purely coincidence? Is the camera designed to play back DVCam tapes? I can't find anything in the instructions that says whether it will or won't.
