I did not have this problem until I got this new receiver. When playing blu-ray discs, the sound stops frequently for about 3 seconds, then starts again. When the sound stops, the receiver display changes from DTS to Decoder Off. Additionally, it does it at the same place in the movie every time. It happens during both action scenes and during low volume scenes. I am running an optical digital cable from my computer's Gigabyte motherboard to my RX-A1000. I also have a new LG blu-ray drive.
Any help would be greatly appreciated.
