same thing here
i can buy/preview music, rent/buy/preview movies, but i can only preview tv shows. since are we unable to buy tv shows? my friend bought one just last night around 8:30.
here's what i've tried:
joined a different wireless network--nothing.
restarted apple tv--nothing.
logged in and out of my itunes account on apple tv--nothing.
closed itunes on my computer, shut down the computer, and made sure nothing was transferring/downloading through apple tv to any other source--ahem: nothing.
HOWEVER, i do see the "buy" button on itunes on my computer, meaning this is related only to apple tv.
probably a server issue. how retarded. thanks, apple. i want my tv back.
