Hi all. I am having a really weird issue with my sony BDV E500W. The sound when on any HD input is very echo-y, mostly for voices! at least that is when you can tell the most. I have digital cable through shaw, and on any normal TV the sound is perfect, but on video on demand it echos, Also through PS3 it echos but only when through optical audio. on the PS3 the sound is fine in analog through the rca's? Is there a different amplifier for analog audio and digital audio? I am stumped! please help!
