Hi -- I'm getting some new digital cable service installed and the guy claimed that the box had a digital sound out connector. Does anyone have anything like this? Also, do any TV channels broadcast in 5.1 sound? I'm wondering if HBO or someone does. (I noticed HBO will be running the first 3 seasons of the Sopranos in widescreen, it'd be nice if the sound was 5.1 too) Admins - please move this to the TV area if needed. My question is more about hooking up this new box though.
