Hi: Please help. Have had the tv/digital cable/surround sound stereo hooked up and all has been well. Until I tried to bring the DVD player into the mix. Can't get the dvd's to play on the tv. Leaving the surround sound stereo out for now, I've got the red-green-blue from the dvd into the red-green-blue of the tv (both Toshiba and about 5 years old) and otherwise all was left as is. Have tried the aux channels we used to use (video 1/2/3/color stream) and it worked at the old place but can't figure it out now. Any advice on how to get this working?
