I purchased a DVD movie - Black Hawk Down. When I tried to play it on my DVD player which audio output plug into a Sony Home Theater System (model: HT-DDW750), I could hear the intro sound. As soon as I click Play Movies, I don't hear any sound through the Sony Home Theater System. When I check, it displayed "PROTECTION" on the front. However, it works alright without the Sound System. I had similar problem with other DVD before. Does any one know what is the problem and know how to fix it ? Regards
maybe it is in your settings? does the sound system have a menu with settings? maybe its set or locked to not play particular media because of copyright issues
