i got The Avengers 2D Bluray/DVD Combo and when playing the movie using the English: DTS-HD Master Audio 7.1 format, the rear speaker has no sound at all. i then borrowed another disk from my friend and same thing. however if played using the French: DTS-HD HR 7.1 or English Dolby Digital 5.1, there is sound coming from the rear speakers.
using a Oppo BDP-83 player and it's internal decoding processor via the 5.1 analog rca outputs to dedicated amps.
i'm not sure why this is so and appreciate some advice.
tks & rgds,
