My Pannys have been pretty accurate in the past but I am now getting a problem with my E500. When I am editing -cutting out unwanted bits etc - it used to be accurate to the exact frame. I then noticed it started removing an extra 4 or 5 frames either side of the cut. I had a huge backlog of stuff on the harddrive so made an effort to get it all on discs. I thought with the harddrive clear I could format it and hopefully get it to perform as it used to. I now find I am losing about 10 to 12 frames either side of the cut. This is really screwing up my editing. Anybody got any ideas or suggestions as to how to get it back to its old self.
