Awesome, thanks so much for this. I’ve now hidden MLB, NBA, and NHL. Much appreciated!
I also hid MobileMe photos (com.apple.frontrow.appliance.internet.dot-mac) – seeing as MobileMe is being retired this month. I suspect Apple will issue an ATV update to remove that menu item too at the end of June. But it’s good to know us jailbreakers can handle this ourselves!
I am not sure what com.apple.frontrow.appliance.internet.internet-photos links to?
I note there is also com.apple.frontrow.appliance.internet.photo-stream (for Photo Stream) and com.apple.frontrow.appliance.internet.flickr (for Flickr.)
