I have a Hopper w/Sling. Locals are included with my account. I also use the OTA adapter (not dual) attached to an outside rotating antenna. When viewing OTA shows directly from the antenna, the PQ is fantastic, especially the 1080i/p channels. Yet, when I record any show on any of the available OTA channels and view them, each present an odd experience. About once a second, the picture and sound flicker, something I never see when viewing anything live. Does anyone have any ideas as to what may be causing this? Recording from the "Dish local channels" does not exhibit the same phenomenon during playback but the PQ is not the same as live OTA.
