This has been happening for a while, but I just finally got around to understanding the full scenario.
When I tune to the Reelz Channel (692) it will always have no sound. I have to go up and select track 1 of closed captioning and then the sound starts. I can turn it off and the sound continues. If I leave the channel and come back, I have to redo it. This issues does not happen on theHDHR software.
I just submitted diagnostics after this happened at 1:16pm here. Channel 692 - Reelz on Verizon Fios
Would like to see this fixed as it's a real pain.
