OK, I'm starting to lose it now. Just bought a new flat screen and the speakers are crap. Plugged my dish 222k optical out into my older denon optical in. All the analog stations play ok. [ Not changing any settings, this is what is happening] Certain HD channels, like AMC, Spike, Epix [ These are what I tested so far] the audio cuts in and out very bad. [ like every other word] Some HD channels play just fine, like CNN, TWC, FX, etc. Wasn't sure where to post this, but I'm sure someone here knows what the h*ll is going on. I would think if it was the denon, all the HD would do this. What is the point of HD if I cannot watch it? I'm ready to heave all this out the door.
