I have DirecTV, and it comes with it.
They have a game of the week on Thursday, but every night they have a show that basically shows bits and pieces of pretty much every game live while the games are going on, and the commentators comment on it. It's like Baseball Tonight on ESPN, but on steroids. When they go to a live game for an at-bat or two, it's the team's local broadcast, which is cool because you get to here people like Vin Scully.
They also have a lot of "classic games" that they replay, shows about the finer points of the game, documentaries, and etc.
Bob Costas does the Thursday game of the week with a random analyst like Harold Reynolds or Joe Magrane or whoever. I think that's a great idea. If one sucks more than the other, you don't have to listen to that duo for all eternity. Like Joe Morgan. And Costas is as good as it gets, so there's no need to rotate him.
The thing I really like about it as opposed to ESPN baseball, is that I think all of the teams get more equitable coverage. On ESPN, it's the Yankees, Red Sox, occasioanlly the Dodgers,Cubs, and Cardinals, and then everyone else.
