Any hints on how to organize IPTV channels by provider (i.e., Pluto, Locast, etc.)?  I know I can make groups but that's a lot of channels to sort through.

In Tvheadend if you go to Configuration | Channel/EPG | Channels, you should see a column next to the channel name called "Number", and by double clicking on the number you can change it to anything you like (after doing so be sure to click on any other field before using the Save button, Tvheadend is kind of weird about that).

You can also highlight a group of channels and then click the "Number Operations" button for additional options.  But don't forget to click the Save button before leaving the page, otherwise all your changes will be lost.

So basically what I do is group channels in groups of 100, so all the local channels are in the 0-99 range, all the satellite channels are in the 100-299 range, etc.  Then I include the actual channel number in the channel name.  For example if I were in New York I might have channel 7 named as "ABC 7 New York WABC".  This puts the information in what for me is the most useful to least useful order.  I first want to know what the network is, that's the most important thing.  Then I want to know the local channel number, on case I want to watch channel 7's news.  Then I want to know what city the station is coming from. that's just a personal preference.  And finally I want to know the station call letters, but for me personally that's the least useful piece of information.  But anyway the point is that the actual channel number in the name, so it doesn't matter as much what channel number I give it in Tvheadend, in fact I could turn off the display of channel numbers entirely (in skins where that's possible) and I would still have all the info.  So that allows me to use the channel numbers in Tvheadend to put the channels in the order I want them to be in.

I got the OTA channels sorted out.  I'm trying to figure out how to manage the IPTV channels which aren't in Tvheadend.  I've got like 1000 channels now with Locast and PlutoTV comingled.  
But thanks for responding.
