so i bought a brand new blue ray player but i already have a dvd home theater system. i plug the audio rca's from the blue ray player into the auxillary of my home theater system and the hdmi cable from the blue ray to my lcd tv. my problem is that when watching a movie in blue ray about half way thru the movie on every movie the sound just cuts out. is there something im doing wrong or is it a problem with my home theater system?? any help would be greatly appreciated.
