[PLUG] MythTV/tuner rescan needed this Friday 2019-08-02

[JP Vossen via plug <plug@lists.phillylinux.org>]

If there are still any other broadcast TV users, esp. for MythTV, be 
aware that TV frequencies have been and are changing.  Get the details 
at http://tvanswers.com/whenResultsZip.asp, but lots of channels around 
Philly are changing "June 22, 2019 - August 2, 2019" or basically this 
Friday.

That said, it's not 100% clear to me what the ideal way to fix this is. 
You'd think that would be all over, but if it is I can't find it.  I 
think, like in this list, fewer and fewer technical folks are bothering 
with broadcast & MythTV anymore.

This would be PERFECT...if it actually had a definitive answer: 
https://forum.mythtv.org/viewtopic.php?t=3012.

This looks good, but it's not clear to me if a) this is a correct 
use-case or b) if it will actually work: 
https://www.mythtv.org/wiki/Updating_Channel_Lineup, see also 
https://www.mythtv.org/wiki/Mythfilldatabase.

Note I use schedulesdirect.org (AKA was DataDirect ages ago) for the EPG.

This Friday I'm planning to:
	1. Backup the DB
	2. mythfilldatabase --do-channel-updates --dd-grab-all
	3. systemctl restart mythtv-backend.service

And see what happens.

If that fails, then:
Applications > System > MythTV Backend Setup (will CLOSE Myth Server!)
	5. Input connections
		[ HDHOMERUN : 192.168.nn.95-0 ]
			Input name: MPEG2TS
			Display name (optional): hdhr5-2us 0 LEAF
			Video source: LEAF Antenna
			Use quick tuning: Never
???			Scan for channels
???			Fetch channels from listings source
			Starting channel: 3_1
			Interactions between inputs: defaults
		[ HDHOMERUN : 192.168.nn.95-1 ]
			Same
Try to watch each channel & note results
Sort through and disable bad channels
	Applications > System > MythTV Backend Setup
		6. Channel Editor


Does anyone have any more or better clues?
Thanks,
JP
