Check for Rentals on Apple TV does not work

I have rented many movies in the past using Apple TV. I have not had a problem until now, right after I just updated my Apple TV software to the latest software v6.0 (6646.65).

Last night (9/28) I rented World War Z. Roughly 20 minutes into the movie, I stopped the move by hitting the menu button. This exited me from the movie and back to the movies rentals screen. I then rented another movie only a few minutes after exiting the first. I had no problem renting the second movie as I did not exit the movie once the streaming started.

A few hours later I went back to watch the move by selecting the movie. The rental option was still availabe. By selecting to rent the movie again and then selecting "Rent and watch now", the system told me I had already rented the movie and I should go to Settings->Downloads->Check for Downloads. This options does NOT exist in the settings menu; however, I found a similar option under iTunes Store->Check for Rentals.

This "Check for Rentals" option does absolutely nothing - or it doesn't show anything if it is doing something behind the scenes. It just shows the spinning lines. I waited all night for something to happen. I restarted my router and modem to make sure there was nothing wrong with networking. Again, I had just watched another movie all the way through with no problems. I sent Apple Support an email with my issue and they refunded my $4.99 for the movie rental.

So, tonight (9/29), I still wanted to watch the movie and I wanted to see if it would work. I went to the movie, selected to rent the movie and it gave me an optionsaying that I had already rented the movie and asking me if I wanted to rent it again. I selected to rent it again. I was able to watch the movie all the way through with no problem.

I ended the movie during the credits by hitting the menu button. I immediately went back to the movie to see if I could continue the movie since I should be able to watch this movie in the next 24 hours. The same situation happened again. I was told I could not rent the movie again, but to go to Settings->Download->Check for downloads. The "Check for Rentals" is doing the same thing.

So, my question is how do I fix this or is there even a fix for this situation? If I can't watch a movie without the fear of exiting the movie for whatever reason and not be able to return to the rented movie, I will not continue to rent movies from Apple TV. I enjoy renting them through Apple TV, but I definitely have multiple options (i.e. XBox Live, PS Network/Amazon, Redbox, etc.). I really want to understand why this is happening and if it's going to be fixed.

Thank you for any feedback!
