I have a m3u that changes and groups channels into sections with different group titles. I'd love to have an automatic process where these groups are reflected in channels. How can I accomplish this?
I'm not sure whether this will work for you but this reminds me of this thread:
I’ve since moved onto a custom program for my needs, but was using Threadfin to pre-filter my source. It allowed you to filter by group-title and I made multiple custom sources with their exported M3Us.
