1. New tapes?
2. Cleaned the head recently?
3. Used the bottle rocket cleaner? (link follows for example)
The odd thing here is you say the screen shows it during recording. Does this have some camera feature or does it happen at exactly a number of seconds?
A consistent problem which I have been having with this camera,(otherwise excellent) has been intermittent and sporadic 'freezes' on the recorded footage on the mini dv tape. This consists of 1-2 sec of a still image and also blank audio. The 'live' footage kicks in again after this still occurs with no adverse affect on the sync of both. The still is occuring on the actual tape itself as it can be observed on the lcd screen of the camera. The only cause I can think of is that the camera may be being temporarily paused by an external radio source such as a mobile phone( or similar) being used nearby. Though clutching at straws here. I have turned off remote control on the camera, but same still happens. Any advice please?
