My provider offers so many channels and most of them aren't of interest to me, not that I'm complaining about that. But I would like a way to cut down on what I see in the guide - cut out the channels that will never have anything of interest to me.

FWIW: I'm on an AppleTV with Flawless using the GSE IPTV and the iPlay IPTV apps (I got both for no real reason in particular.) I do have an always on computer available if I need to host it somewhere locally.

I've tried iptv-epg.com and epgguide.net but didn't find either very helpful - I spent a few hours today messing around with them to no real avail.
