NVIDIA-SMI 340.98
Ubuntu 16.04.1 LTS
HDHR Prime
Separate frontend and backend

If I start live tv on a 720p channel.  It starts and plays fine.
If I switch to a 720p channel after live tv has been running, the video begins to stutter
Also
When I start livetv, on any channel, the av sync is less than 1.
If I switch to a 720p channel, the av sync becomes 3 or more and the video stutters
If I switch to a 1080i channel, the av sync is between 1 and 2 but I do not see a video stutter.

In any of the instances above, hitting pause clears the stutter and the av sync goes to less than 1

When the stutter is happening, the frontends logs the following.
