I haven't been on the forum for a while, but have run into a problem that has me stumped. I have two 50x0s on Comcast, and have discovered (while trying to record "The 4400" for my wife) that I get no sound on that channel (USA Network). I get sound when tuned directly through the TV, so it's not something Comcast will fix, but whether live or recorded, I get no sound through either of the two ReplayTVs. All three devices go through the same splitter/amp, are wired similarly, etc.
This has me stumped, and I know of no way to diagnose it. I've power-cycled the RTVs, checked the sound on adjacent channels (all channels, actually), and it's fine. But one Channel -- 54 -- has only the tiniest hint of sound when turned to max volume, along with some hiss and crackling (the kind you'd expect when a "silent" channel was turned all the way up). I've dumped the recordings with DVArchive and the sound is non-existnant there too, making this an RTV tuner problem, I guess.
But why in the world would the RTV eat one channel's sound, with no other problems?
(I did search for this -- it sounds a little similar to this thread
, which never got a resolution. )
