Page 1 of HELP WITH MACROVISION FOR DVD PLAYER TO RECORDER!!!

I`ve recently bought the macrovison cable from Sonel and it works with videos perfectly. Am able to record pre recorded videos with the copyright protection appearing. The only problem I have is that when I connected a dvd player up to the dvd recorder using the macrovison lead it made the dvd `jump`. The copyright seemed to disappear but the dvd still didn`t record perfectly. Could it have been the dvd player I connected up or will it not work with dvd player to recorder???
