I've had a very strange problem with my Denon AVR-X4100WE2 receiver. When I play my US Blu-ray of 'The Favourite', the receiver is shutting itself off at 50' 41" into the movie at the point when there is a loud gunshot on the soundtrack. The volume is set to 68 dB, which is my usual volume setting for Blu-ray playback and is certainly not excessive. However if I reduce the volume setting to 67 Db, it is perfectly OK. I repeated these tests several times with consistent results. I also tried the disc on both my Blu-ray players with the same result. The soundtrack is DTS MA 5.1 and one player does the decoding whereas the other player passes the bitstream to the receiver to do the decoding, so it makes no difference whether I have the decoding done by the Blu-ray player or the receiver. I checked the troubleshooting info in the owner's manual, and it does suggest reducing the volume as a possible solution. That is probably intended for cases where the volume setting is clearly too high and could damage the receiver (not to mention the speakers and the listener's hearing), but it seems ridiculous when the volume setting is the one I use without any problems for all my other Blu-rays. Can anyone suggest a possible explanation for this?
