Ok, I went to the Help screen, and applied the Community Gracenote Map, and my Gracenote source went up to 80, and the NON Gracenote one went down to 166.
Unfortunately, I only originally installed the first version of FastChannels last night, and I forgot to take a screen-print of how many channels were in each at the time. Not sure it got them all back, but I'll deal with it for now since I am still learning this type of stuff to go with Channels! For years, I just built my .m3u lists manually with Notepad++, but it's gotten far too hard and messy to keep up with it.
Boy, am I learning... lol.
P.S. I THINK after initial upgrading, all the Gracenote channels migrated to the Master m3u feed. But, when I checked them in that, they didn't have any matches so there was NO guide data for them in that Master feed. There wasn't even the dropdown list for "All Lineups" etc, so no way to match them in that feed.
