Outraged by lack of info in iTunes about iPad HDMI compatibility?

Question

I bought an iPad 2 as well as the HDMI adaptor so I could download movies on the go on my iPad and also watch them on my HD TV.
Turns out that you can't watch every film you download through iTunes on your TV. So, I download The Princess Bride from iTunes, which plays on my TV fine. And then I pay £6.99 for Moon, which all my friends tell me is brilliant. And no. I am not allowed to play this from my iPad to my TV
Now, I know this is not necessarily Apple's fault, but due to the Canute-like inability of certain studios to engage with the modern world and what consumers actually want.
However, I do find it obnoxious that in the iPad version of iTunes there is no mention of this fact BEFORE you buy a movie.
Fine, invent some cockamamie rules about which content I can watch where - but at least let me know about it before I pay you money.
Has anyone else noticed this? Is anyone else as annoyed as I am?

There shouldn't be any licensing restrictions since you've purchased all of that.
The addition of the copy protection logic certainly complicates the issue and you could have incompatibilities between your TV, cable, and iPad. One suggestion I've seen is to just power cycle all of the devices.
If that doesn't work, check out the links in this thread: HDMI Digital AV Adapter / FairPlay Movie / Display not Authorized
If that doesn't work, contact Apple. It should work.
