What Could be causing this problem ?

I also sometimes get unable to playback black screen error message

Next time it happens submit diagnostics from settings. Live TV From HDHomeRuns buffers on the device, so your Channels DVR Server shouldn’t matter.

You might also want to check how much free storage is on the Shield.
