I used to use a Samsung se204n dvd +/-RW burner but it recently broke down and I had to replace it. I bought a Memorex 32023223 20x DVD but for some reason all the dvd software I have will not work with this. Fo some I get an error "semaphore time out dvd decryption key not found" on others it just will not open the dvd to break the protection. I can burn already decrypted movies I had on my hard drive fine. I can also play a movie with no problems. Is there something they are putting in new dvd burners to disable the decryption software? I have been using burners for a few years now with no problems before. Please Help! Thanks and have a great day.
