After I add the new M3U line from xtream editor into TVMosaic then I seem to be getting the EPG ID in place of the channel name.
Here's the output of both the original and then reworked M3U's.
It looks like tvg-name is being read in as the channel name which is different between the two M3U lines. At the end of each line it's got the actual name I want but TV Moasaic doesn't seem to be picking it up from there.From Original Provider
