Comment (by deadletterfile@…):

 Commit 12c443eb1cd22cecd257ea61984fa2dfb31d4992 on the fixes/0.26 branch
 is what broke over-the-air broadcast scheduling updates for me.
 Specifically the additions to DVBSignalMonitor::UpdateValues(void)

 I commented out the added lines and this compiled commit worked as hoped,
 with over-the-air scheduling updating as expected. I learned in testing
 that all station schedules update at a minimum every three hours, and
 extend out at least ten hours.

 I did a “git checkout 7f71e02467f52d1e3336b8badeee31d3235bb42f“ and “git
 status”[[br]]

     HTTPLiveStream::GetLiveStreamInfo fixups.

 The above DVBSignalMonitor::UpdateValues(void) lines were again commented
 out and I am testing. I expect success.


 On the master branch, I did a “git checkout 7f71e02467” and “git status”
 then compiled.
 Over-the-air broadcast schedule updating still fails for me. I am using
 Fedora 19 for the master branch. /dev/dvb/adapter0 is a HD-5500 card;
 adapter<1 2> is a HVR-2250 card. The above compiles and tests were on
 Fedora 18 with the same machine.

 Below is a cut/paste with date added to a SQL query of my test results on
 the master branch:[[br]]

 As you can see the station schedules appear to initially update ( I
 checked the program guide on mythfrontend), but then no updates over a six
 hour period. The code I altered in fixes/0.26 is not in master, and I have
 not yet attempted to find where my breakage occurs in the master branch.

 I hope you might be able to look at fixes/0.26 based on my analysis. If I
 can be of assistance, let me know.
