i seem to be having an issue with dialogue that should be thru the center channel but is coming thru the left rear speaker in certain movies. both films are new releases, american sniper and jupiter ascending. american sniper was sporadic, but jupiter appears to be throughout the whole movie. sound thru the other speakers seems normal. other movies are just fine so far and sony customer service said there's no updates regarding this issue and said a factory reset would likely solve the problem, however it did not. i am using a bdp s5100 player. if anyone has any thoughts, before i purchase a new blue ray player i'd appreciate it a great deal.
