Instead of wearing out your poor Apple TV, you can easily check to see when the new Apple TV update has been release.
1. Download Page Update Checker extension for Firefox
https://addons.mozilla.org/en-US/firefox/addon/920
2. Install the extension
3. Visit the update xml with firefox
http://mesu.apple.com/version.xml
4. Right-click (ctrl-click) and select Monitor for Updates
You will be notified with the xml changes (and thus the update is available.)
Alternatively, you can use a notify-by-email web service such as http://www.changedetection.com/detect.html to email you when a page changes.
Enjoy.
