I gave my nephew my older Radio Shack receiver that is several years old and has the old Dolby Surround (two front and two back speakers, no center channel and no LFE channel). I remember hearing good surround from VHS movies I rented encoded in Dolby. Here is the question. I also gave my nephew a DVD player and it is hooked up to the receiver with the regular left and right channel output. When he plays a movie with Dolby Digital 5.1 is there also the old Dolby Analog signal present? Will he hear Dolby Surround or just stereo?
