Prismcast and MGM+ Live Channels (all four of them)

Playground Hacks
#1

For context, I'm very new to this.

I have Prismcast up & running. Thankfully, the pre-configured services (HBO Max, YouTube TV, and Paramount+) were fairly straightforward & easy to setup. Using the UI, I've added MGM+. The main channel worked and showed in the live guide correctly. But there are 3 other live stream channels in MGM+ (MGM Hits, Marquee, and Drive-In). When those didn't show up, I went back and added/created a New Channel for each with the corresponding url. The added channels work but the live guide now looks like this:

I think my error may be in the "Channel Key" naming convention I'm using. As I understand, doesn't the Channel Key have to contain part of the name from the url or am I way off?

You need to use the Station ID field to put in the correct Gracenote ID for each station, or map the stations manually in Channels or other tools. After you do so, refresh the m3u in Channels and delete and recreate your guide database to get everything corrected.

Good to know & learn. I'll start looking up how to do that. Thank you for the reply

UPDATED UPDATE: Got it working. Using Gemini & setting up MGM as a separate (text based) Custom Channel source made things way more complicated than need be. Out of frustration, I got rid of it. Then I gave things (the suggestions posted) one last go-around for sh*ts & giggles - and it WORKED! The channel logos are there and the guide is populated. Sweet!

Thank you all. Disregard everything below this.

UPDATE: (kind of) Right Back Where I Started:
Decided to have Gemini help out with this issue. It took me down a maddening/mind-melting rabbit hole for several days - just to end up back here. I accept full responsibility, as I'm not very savvy when it comes to this.

It had me create a separate Custom Channel for MGM+ using text as the Source.

I noticed the stationid wasn't a match to what I have setup in Prismcast, but Gemini assured me that didn't matter - as the text points it to Prismcast anyway. The channels (MGM+, MGM Hits, MGM Marquee, and MGM Drive - In all work when selected.
The issue remains to be guide populating correctly. I've tried setting up & using "Change Providers" using several different ones. I settled on Dish because it had all MGM channels so that I could follow babsonnexus's suggestion to map them in Channels and delete/recreate my guide database (thank you again babsonnexus).

Here's what the channel mapping looks like using Dish as a provider:

At this point, I'm not even concerned about the logos. (I think) I can manage getting that corrected. Honestly I rarely even tune in to the premium channels I already have set up (HBO, Showtime, and Starz.) I just like seeing what's on/up next to see if it's worth switching over to the app. I just need (non AI) help figuring out what I'm missing/where I'm going wrong before giving up on adding MGM.

Thanks for letting me vent

Did you try and search for the correct match within CHannels manually?

Ignore WITF, I don't have MGM based channels, but when you go into the channels, click the dropdown on the right and select "Search All Lineups" and then start typing the channels you are looking for.

If you are successful in finding the right channel, look at Channels exported Master M3U and you can find the individual Gracenote id that are the correct ones to then insert into PrismCast so that any future re-setup or modifications ensures you are pulling in the correct guide.

I thought I did - at least part of that. I didn't think of exporting the Channels m3u and looking at that though. Thank you for the idea & the reply.
