Public bug reported:

I did a fresh install of Mythbuntu 16.04. I have 3 identical Hauppauge
Nova TD dual USB DVB-T tuners that use the DiBcom 7000PC driver. After a
reboot if I try to watch live TV I get a message "All tuners are
currently busy".

In addition to "all tuners are currently busy" my mythweb has all the
headers in place but the Listings page has no content and says: "Warning
at /usr/share/mythtv/mythweb/modules/_shared/tmpl/default/header.php,
line 12: !!NoTrans: Cannot modify header information - headers already
sent by (output started at
/usr/share/mythtv/mythweb/modules/_shared/tmpl/default/header.php:152)!!"

After a backend restart 'sudo /etc/init.d/mythtv-backend restart'
everything works.

This is possibly related to tuners not being ready before mythbackend
starts up. There are a few possible workarounds, but I haven't picked
one simple enough yet.
