Backend becomes unrespnosive when viewing Live TV.

Hi Everyone,

When I try and watch LiveTV, I just get a blank screen for a minute or so. After that, I am then retued to the frontend's menu. If I try to watch Live TV again, I get the message "All tuners are currently busy". I think it's a backend problem because MythWeb also becomes unresponsive. I need to reboot the backend to use the system again. There are no problems scheduling recordings and watching the recorded programs. Also, this issue did not occur under Mythbuntu 14.04. (I am now ruing Mythbuntu 16.04 - fresh install.)

Any help will be greatly appreciated.
Thanks.

(FYI: This is just the first of many, many, many problems I am encountering with Mythbuntu 16.04.)
