I've added a new OliveTin/Project One-Click Action to automate everything needed to use DTV with ADBTuner.
This includes:
- Capturing the deeplinks for your set of specific DTV packages, including locals.
- Converting those deeplinks into a JSON for use with ADBTuner.
- Adding Gracenote Station IDs to each of the channels in your custom list.
- Adding those virtual channels to your ADBTuner installation.
- Adding whatever ADBTuner Custom Config you'd like to use to ADBTuner.
- Importing those channels complete with DTV channel numbers and GracenoteIDs into ADBTuner.
- Creating a CDVR Custom Channels Source with that set of ADBTuner channels call
ADBTuner - DirecTV

This Action should go live tomorrow (08 Dec 25)...

from ADBTuner, I recall it was fairly trivial, since that value is already available as an internal variable.
