I add an m3u and them go into channel mapping and manuallly map to epg channels. Most of them I choose "Search all lineups". I just go done adding in a bunch. I did a guide refresh and about half of my mappings are now gone. Do I have to map to a single lineup or is it ok to "search all lineups" when finding a channel?
It says DVR: X-M3U at the top. I did not pick a zip code based lineup at all. Just immediately starting mapping.
