You don't have IPTV manager installed.

Didn’t you say it was either/or? Pseudo TV or IPTV Manager but not both?

You DO NOT configure IPTV Manager, it's a passive utility. If you are using IPTV Manager as a standalone plugin you select it to configure IPTV Simple; if you are using PseudoTV Live you select PseudoTV Live to configure IPTV Simple. It's one or the other...

ie, You're using IPTV Manager alone or You're using PseudoTV Live which can integrate with IPTV Manager via the import function. 

If you want to use PseudoTV Lives import function, you can either directly import any Third-Party m3u/xmltv pair, or if the plugin supports PseudoTV Live you'll be prompted to add the channel to the recommended list. Then you select the channel from the "Recommend" drop-down list.

Hope this helps clear things up. =)

PseudoTV Live piggybacks off IPTV Manager.

Alrighty, making progress. I installed IPTV Manager then did a clean start of Pseudo TV. On restart of Kodi I get the dialog that a compatable plugin was found (Discovery+) and I select yes to add it. Now under predefined channels I have the "Recommended Services" option where I can select Discovery+ "Imports".

After that I seem to be at a stand still. Nothing in my guide and I get a pop up that I don't have any channels configured.

What is choosing the recommended services supposed to do exactly?

At this stage its really not all that important in my use case since, being in the USA and not having live TV as part of the Discovery+ website, there really isn't any reason to bring Discovery+ into PseudoTV. Just curious how its supposed to work.

Thanks for all your help @Lunatixz
