catching up on some DVRed shows, I've had a few that go for 10-15 minutes with no dialog. It's an HD satellite feed [Dishnetwork], though some may have been OTA [I have an antenna tied into my system and the Dish DVR allows OTA tuning, but I usually only revert to the OTA feed if I'm DVRing 2 shows off satellite already]. It's in 5.1, and the center channel is working, ie providing background effects and music, but the dialog is missing from the 5.1 feed, and it likewise missing from the analog downconversion if I switch over to analog inputs, or output through my TV speakers. I specifically recall the 2nd episode of Shark and Numbers exhibiting this, so it's not a network specific problem. Anyone else experience this? Could it possibly be a receiver problem? I kind of ruled receiver problems out as the center channel background was there, and the dialog came back in at the same spot [usually accompanied by a 'splat' indicating a change in feed], even if I rewound or restarted the program.
