Ive had this receiver less than a year (been using it for less than 6 months) and I first started having issues with the video cutting out intermittently and frequently- especially during 3D movies. I am using an Oppo BDP-103 and a BenQ W7000 (both are also less than a year old and been using all for less than 6 months). So, I had plugged the projector directly into the Blu-Ray player and that seemed to cure the video cutting out issue. Luckily the Oppo has 2 HDMI outputs. But just this week I tried to watch The Avengers in 3D with a buddy over and the sound was cutting out during the whole movie. Very frustrating to say the least. It would cut out for only a few seconds at a time, but it seemed random. It wasnt necissarily at very loud scenes, and it wasnt at only quiet scenes, it was all over the place. I'd say it probably cut out on average at least once every 20-30 minutes. I verified all connections are tight, even switched the HDMI cable from the Oppo to the Denon to no avail. If it matters, I am running all 11.2 channels with the 2 height speakers thru an external amp. The thought crossed my mind that perhaps it was the internal amps in the Denon cutting out, but when the cut outs happened, sound didnt even come from the height speakers. I know those speakers are not really used very much, but when the sound cut out, it was dead silence.
Is there a known issue with the 4311 that causes this? What is the fix (if any)? Any help at all would be greatly appreciated!
