Hi Paul,
After numerous correspondences and pleading with Canon service department i sent the camera in again.
Canon removed the “electronics board” and replaced it with an entirely new board. TO date I haven’t had any problems.
I think the ultimate solution, if you can afford it, find a Firestore drive and shoot on tape and record to the drive at the same time. At the very least you will have two sources from which to digitize. The inherent issue is that the $1000 cost of the firestore is 1/3 the cost of the entire recording device.
