How to AppleTV without internet?

Question

I'm looking into buying an Apple TV for the wireless connection to my iPhone 4S to stream videos, games, etc.
But now I'm curious about all the downloaded videos I have on iTunes library that I would like to have at home.
Here's the kicker- no internet at home, only at work. So I usually download during the day, sync my phone and watch when I get home. But of course, I run out of room to keep everything I want even with 160GB iPhone (mostly music).
So here's the question: Is there a way  to move purchased movies from my computer at work to my Apple TV at home AND be able to do all the fun stuff like wirelessly play games on big screen from iPhone?

Answer 1

AppleTV has no storage.
Unfortunately current models need internet to play protected iTunes content as internet authorisation of playback is needed.
If you have a computer at home you could transfer your downloads from the work machine to the home computer iTunes library.  You could then use Home Sharing for AppleTV to access the computer iTunes library.  You would then need a local network connection between AppleTV and computer plus internet access for AppleTV.
Potentially if your iPhone has internet you might be able to enable a wifi hotspot (or share internet via USB) for the computer, and either allow AppleTV to connect to iPhone too via wifi or share the computer internet (from iphone) over ethernet to AppleTV.  This should work in theory and provided playback is via AppleTV Computers icon the media should just play opver the LAN not the internet, but with iPhone internet used to very briefly authorise the playback.
While it should work I can't guarantee it, and there has also been a post where someone used their iPhone internet allowance quickly using Home Sharing even though such dats should be local not traversing the internet.
In all honesty, I would be wary without a router and decent internet.
