I have a PV500 and I've been having several issues. 1. It overheats and stops recording. 2. the sound randomly cuts out. Are there any of you who have problems with it like I do? Did I just get a bad unit? I think it overheats because there's no airflow when in the holster it came with. Any ideas how to overcome that at least? I think the sound problem is actually in the camera itself but I'm not sure. Any ideas would be appreciated.
