i hooked up my tivo via optical to my reveiver, but some how the vocals are coming out of the right and center channel for some of the channels. anyone know what might be causing this? im using a rxv 2400. everything is hooked up correctly. it doesnt happen with dvds. there seems to be some sought of distortion coming out of hte surround and left/right speakers while watching some channels. sounds like some sought of scambled signal. its very low and cant be heard unless u put ur ears to the speakers. its not a big thing but it bothers me. any response would be appreciated.
