I've got MLB.tv on my AppleTV as well as my iphone and iPad. I never watch the games on my iPhone, but it's great for streaming the audio feed of the radi broadcast to my car stereo when I'm driving. I wish the NFL had an app like this, but I think they want to keep football games as a bar activity. I'd never go watch a non-playoff baseball game in a bar, but I've gone to bars plenty of times to watch football games simply because my team's game wasn't on TV that week.
