Hi All, wonder if anyone can advise on the following. I was given a BD-P1500 and it is having problems playing DTS Master/ Dolby True. I have it connected with an Onkyo 605 Amp via HDMI and then to the tv. Once a movie starts I get crackling sound/cutting out throughout the movie. I have tried it with basic Dolby Digital 5.1 & DTS and its perfect. I have also got the lastest firmware update. Any ideas what could cause this?? Thanks to all
