Yep, that's what the Comcast agent told me when I signed up for the service this weekend.
She actually giggled and replied, in broken English, "Yes, it is included."
So it's disappointing to learn that Comcast agents either 1) aren't fluent in English, or 2) they don't have accurate information.
If I'd known this, I might have signed up for MLB.TV instead.
But I do enjoy Extra Innings, and I can listen to every game with my At Bat subscription.
Still, it's deceptive -- the commercials clearly state that MLB.TV is included, with no qualifications.
I too expected access to mlb.tv based on the commercialls. Disappointing for sure. I would have gone the online route had I known. Guess I should have double-checked.
