The difference in filenames for the recordings is due to the season / episode number not being available in the EPG data at the time for the earlier recording - this could be to interim data provided by Gracenote and updated later on - We do have an issue that is being corrected where updates to EPG metadata for already scheduled recordings are not picked up until the Plex Media Server is restarted.
If this continues to happen, I suggest raising it as per the advice given on this Live TV and DVR pinned forum topic Reporting Plex DVR Lineup Inaccuracies - Live TV & DVR - Plex Forum and for the Plex for iOS mentioned playback issue, also including the Plex for iOS logs and zipped media info xml from the Plex Web Get Info and debug server logs.
Yes - All access to the server from public IP addresses must be authenticated. This has been the case for a long time
Are there any debug server logs captured after a 1.29 PMS crash?
Could you expand on this ? Which hosts files? What corruption
Sorry I have not gone through the whole forum thread - please point me to specific posts
