Apple ID Apple TV not getting along

[WhiteShadow]

I cannot sign into my itunes account on my apple tv.
I have the appleTV synced to my brothers computer which has his own apple ID.

What I want to do is log into my apple ID on the appleTV, since I have a large gift card on the account, but appleTV is not happy about that.

Is there something that I am missing? or is appletv only able to access the itunes account on the synced machine? (which sucks).

please can someone help.

While I love my ATV I can tell you it is picky about which computers it will sync to and such. If you're sync'd to a library on your brother's computer it'll expect you to break that link before you use your own ID. That is at least what I've experienced thus far.
