Resident Geniuses: I am new to this forum and am thrilled to see that I might finally have arrived at a place where I can get some answers or at least enlightened guesses, which are almost as useful. Here's my current problem, so far unsolved: I have a Sherwood Newcastle A/V receiver of which I am very fond but which seems to be having a digital signal dispute with the new DBS system I had installed earlier this month (two Hughes sat receivers and a 3-pole dish). I am overjoyed with the video quality of DBS and generally quite satisfied with the audio quality, but my A/V receiver is shutting off the (optical) digital input of the Hughes Executive Director model sat receiver that's stacked with my HT gear after 4-5 seconds. I choose a program that DIRECTV's guide assures me is encoded in Dolby Digital 5.1, I choose the alternate audio stream that carries the DD 5.1 data --- and, after about 4 seconds of glorious 5.1 surround, the receiver (and I'm still not sure which one, the sat receiver or the A/V receiver) shuts off the sound as if I'd hit the mute button. If I toggle the DD button in the Audio menu of the DIRECTV setup menu on and off after each shut-off, I get another 4 seconds of 5.1 and then it shuts off again. I could sit there and toggle the switch on and off 1800 times or so during a standard film broadcast, but I have better things to do with my hand tendons than this. The Sherwood Newcastle tech support folks say they never heard of this problem before, and nothing they suggested (unplugging the other digital input, a coax line from my JVC DVD Video/Audio player, replacing the optical cable, checking for dust, etc., in the optical jacks) solved the problem. For their part Hughes techies, after 3 or so hours on the phone having me flip through numerous setup and initialization procedures, concluded lamely that there must be some sort of incompatibility between their sat receiver and my S-N A/V receiver that is not resolvable short of re-engineering. SO I guess my question is this: Am I being snowed by these guys? Have you-all ever heard of such an 'incompatibility' bewtween two electronic components operating in the digital domain? And since the Sat TV sales company that got me the Hughes receivers doesn't carry any other brand, is there any workaround I might try that would restore that glorious but Sisyphean 5.1 surround sound from my DBS? Finally, assuming none of the above works, is there a) any sort of encoder-decoder I could plug into the line between the Hughes and my S-N that might mediate this dispute, and b) a decent-sounding newer A/V receiver under $250 with a minimum of 70W/ch that people around here like a lot? Thanks for yer patience, and boy am I glad I found you folks! --- Johnny Vee.
