So lately.... probably over the course of the last few months or so while watching a recorded show on my Sony TV, the video would lock up and cause my TV to become mostly unresponsive and would require a forced reboot by unplugging the power.
This only happens while watching a recorded show. My DVR is running on an nvidia shield.
This is a log around the time it happened last.

If I search back in the log.... this happens quite often and its a different IP address each time.
IF this is indeed a DoS attack why does it ONLY happen while watching a DVR'd show using the Channels app.
