The missing episode is now available, but you have to go the Search option and type "FEUD". You'll see it in the matching results. Why it is so troubling to create links in the standard pages, I can only guess.
It happens so often for so many networks and shows --- my guess is that providers can't see the actual results when they post materials. So it is hard for them to see when things aren't right. If I'm wrong, things are worse than I imagine.
Episodes 3 & 4 are still not in the program folders. I can access them (SD or HD) via Search and keyword "FE"
Koty1 - For FOX, FX and FXX shows the episode description (the "OK/Select" or "info" button) always ends with "HD version.", even when SD content is selected. If it is truly the HD version, "HD" will appear in the upper right where closed captioning (CC), Dolby digital and the parental rating (e.g. TV-MA) icons appear. I hope this helps and you can catch-up with the program.
