Hello - hoping someone might be able to shed some light on an issue we are having. As we sat down to watch Game of Thrones on Sunday we noticed that our sound was not very good. Our amp was showing linear PCM. We were taping on another box and on playback it was the same. Crave 1 and HBO 1 & 2 are doing this. Crave 3 and many other stations are fine and coming through as Dolby Digital 5.1 and sound great. I checked a recording I had from months ago when 301 was still the Movie Network and it was fine. If it is an issue with our amp I would think all the stations would be like this. Any ideas? We have to watch on demand to get the proper sound. Any suggestions would be much appreciated.
