Channel Scan turns EIT usage back on while guide data comes from somewhere else already, resets visibility and other values.

[dekarl@…]

I have a setup with mixed guide data from Xmltv and EIT.

After the initial channel scan all channels with EIT present get EIT usage enabled. I turned EIT usage off for the channels I get via Xmltv.

On the next channel scan EIT usage got automagically turned back on although there is guide data in the database. (which doesn't work and is unsupported, see #1770)

This happens still after configuring Grabber+EIT via mythtv-setup (should not matter, the channel scan should only care about data being there or not, might be inserted via mythfilldatabase from cron because its from nxtvepg or whatever)

I'll commit a fix which preserves use_on_air_guide if xmltvid is set for 0.23. Further fixes require DB updates and are scheduled for 0.24.

Bumping to .25 as I believe the remainder of the changes mentioned in IRC require substantial rework.
