Really odd behavior with sports (Pac12) channels

I seem to recall another thread with similar symptoms but now I can't find it. Anyway, this is odd behavior on all of the Pac 12 channels...

Streaming is perfect until a commercial break. Then the channel shows a screen as in the 1st pic, video freezes, the progress bar appears with the spinning circle.

Then, this screen will disappear and video will resume without sound for the remainder of the commercial break.

Then, when play resumes, sound returns. However, a time-shift has occurred and the video is about 1 1/2 minutes lagging. See timeline pic 2.

I just sent a diagnostics report. Curious, huh?
