Is that custom channel bug you mention what is causing the EPG to always number the channels starting from 1 and up, rather that the channel numbers specified in the PTVL settings (despite having that enabled in the PVR settings)

No, Custom channels (channels created in the channel manager). Were removed from PseudoTV's channels.json during periodic channel updates... should be fixed now!

As for channel numbers/ordering.... anything to do with channel ordering is handled by Kodi's PVR, you'll have to check your settings. There are a few that yield different results.

If you want to sync "channel order", channel numbers from PseudoTV Live are ignored but the ordering is maintained.
If you want the exact channel numbers from PseudoTV to reflect onscreen, you'll have to enable syncing order and numbering from the backend.

I believe any changes will require you to clear data from the same PVR settings menu.

@ThorC1138 Also make sure in IPTV simples settings that you disable "Only Number by Order"
