[mythtv] DVB tuning broken in current SVN

[Ian Caulfield]

Hi,

I've updated to svn 7389, and nothing seems to happen when the backend 
tries to tune - doing some digging, it looks like (as all the PMTs for the 
mux are transmitted on the same mux) the PMT for the wrong program is 
being picked up, and no further ones are considered. The DTVSignalMonitor 
seems to wait indefinitely for the PMT to arrive, but it never comes. Will 
try to debug it some more.
