It’s been a while but I’ve had a Pioneer DVD player and never had a problem. I’ve bought an Electrohome DVD-816e to fill the gap for bedroom movie time and when i pop the dvd in it says “Prohibited by CSS”. What is there to do? I don’t understand why this drive won’t work. Is there any listing of dvd players that won’t do this for my copies because so far my Pioneer was flawless for the last 4-5 years.
