VCR picture fade Can't Post

Following the advice posted earlier on this board I began taping from one VCR to another successfully. While watching the recording picture on a TV, I noticed that the picture periodically faded dark and then back to normal.
Does this indicate a malfunctioning VCR or some sort of copy protection system built in to the VCR?
Thanks

Just as you thought it is copy protection. I haven't seen copy protection for some time, since many methods kept you from watching the original tape on some machines.
A couple of suggestions, try switching machines, i.e. use your record machine as the playback, and the playback as the record machine. Sometimes even the same brand same model machine will work. New VCRs might work better than a 10 year old model for the playback/record machine. There was a time when VCR companies were manufactured to prevent you from coping copyguarded tapes, newer cheaper machines might have droped that technology. Along the same line of thought, if you can find an early 80's VCR it might work if it was built before copyguard technology.
A second option use Audio/Video inputs/outputs as opposed to RF inputs/outputs newer machines will have these. Also use the shortest cables you can find, there will be less signal loss, and therefore lessen the chance the copyguard will work.
A final costly fix would be using a frame sync. You can pick-up one on E-Bay for $150, No guarantee that will work. For this to work you would also need have a playback and record deck that that use Video/Audio inputs/outputs with phono jacks. The frame sync has BNC jacks, so you would need a BNC/Phono adaptor (phono socket to BNC Plug), which you could also get online or at your local Radio Shack, make sure you get the proper gender male/female on the adaptors.
Hope that helps.
