Welp, followed the instructions, upgraded all the apps, upgraded to Frodo 12.3 and now we have add-ons.
Starting to watch some stuff on 1Channel, but having some issues with video being stuttery and audio slightly out of sync. Have futzed with the video settings a bit, but not having much luck correcting. Any suggestions or is this likely just an issue with the stream?
Thanks again to both of you for all the help.
