Panasonic PV-DV102

there are 2 causes why your camcorder is eating up the tapes; either the tape head is dirty or there is a mechanical fault inside your unit (something might be misaligned that causes the film to be sucked in).

try to clean the tape head of your unit by using a tape head cleaner, it is like the tapes that you use with the unit but instead of a film there is a cloth like material inside that is used to clean the tape heads to avoid the film sticking to it

if the issue still persists then you should contact your manufacturer and set up a repair for the unit
