I wonder if you can help, I have just painstakingly ripped all 65 episodes and specials of Only Fools and Horses. I have not yet watched any of these episodes Plex lists them all as unwatched however for some reason it wants to start playing this show on the last episode.
I have confirmed the correct airing dates have been applied the first episode details shown below:
Are you sure your not accessing the Recently Added from the HUB.
Drill into the series/season1 then play episode 1. That should get it listed on your OnDeck HUB.
Remember though, autoplay will not list by air date. Only the OnDeck… Unless something has changed over the past few updates…
