I have a Integra dtr5.3 and comcast digital cable box. Using a optical cable from the box to my video 3 input. When i first got the digital cable the HD channels would auto detect the Dolby Digital sound. Now I cant get the DD anymore. I think my little brother might have messed with something but i cant seem to figure it out. Does anyone have any idea what to check for in my receiver settings?
