1st Gen Movie Menu Items Missing

I have a first generation Apple TV. However, recently I am unable to purchase Movies, TV shows etc because the Menu Items to do so no longer appear. There are main menus for Movies, TV shows etc but there are no sub-menus beneath them to puchase a movie or watch trailers etc. I have switched the Apple TV on and off, logged out and back into my iTunes and WiFi account, done a complete factory reset of the Apple TV and reconnected to iTunes on my MacBook but still the Menu options to purchase movies etc have not reappeared. iTunes on my Macbook syncs perfectly with the Apple TV and I can watch movies that have been synced, I just cannot buy or view movies/TV shows etc because the option to do so are not on the respective menus. Very frustrating. Any help appreciated.

Cheers,
