I've been playing around with Pluto, Plex, Samsung, etc. and I noticed that after setting a starting channel number, for example 1000, the original channels are still in my guide. So I have Pluto channels at 1000 with the images for the channel logos, and then at 6000 I have the same channels and guide info, but no channel logos. This has really messed up my DVR settings, because it is seeing a lot of channels that aren't actually there. Anyone know how to clear or reset the channel numbers?
Always been that way.
Any time you remove a source, go to Settings > Live TV & DVR > Guide Data > Maintenance 
> Delete and Recreate Database
That will clear the old channel numbers so that a new source can use them.
Thank you, that worked!
