First of all a warm thankyou to PD technical support who did not even acknowledge my plea for help which I sent last week.
I seem to have found a solution to this problem by accident, no thanks to them.
I was getting the above error message at random points. Infuriating as I bought this software thinking it was more or less point and shoot as I'm not a wizz on the PC. I have about twenty VHS tapes of 3/4 hour length which I want to transfer to discs. These are straightforward store purchased blank tapes by Memorex TDK etc onto which I have transfered home made films taken on camcorder of my kids and family over the years.
Researching the problem on the net I discovered that the error is caused by 'noise' or whatever on the tape which is picked up by PD and misinterpreted as copyright protection. To say I was frustrated by this glitch is putting it mildly. My PC is in use during the day and my plan was to set it up to tape at night when we were all in bed. It became a guessing game when I came down in the mornings wondering how long it had managed to tape before saving the universe and switching itself off.
Ok so here's what seems to work for me.
When the dreaded error box appears save it. Rewind your tape to the point at which it stopped. Click on the PD record button without doing anything else. Recording begins again but you will notice that the 'Counters' on the PD screen will not be moving (Recorded video length, and the counters next to the pie graph of disc space).
At first when I restarted recording and noticed that these counters were not running I thought that the programme was not operating so I closed PD down and started again. This simply caused the error to occur again. In fact it was recording all the time!
I have copied 8 tapes over the past few days and it has not stopped due to the copyright error once!
