Another EI option...
This year after testing it out, I decided to go with MLB.com for their EI operation version. Finally cost for the year was $99 (I went with the $20 off option although I had to subscribe to Sports Illustrated for $20).
First, I would have to say IF you want to watch baseball ONLY on your home TV, the DTV EI is the package to get.
However, the MLB.com version does have a lot going for it. First, I can watch it on my iPhone, or I can choose to watch it on my computer (or on anyone's computer if I'm visiting.) AND I can watch it on my HD Samsung TV almost just like EI.
I have a new Apple MacBook Pro that has a HDMI output to my Samsung TV (1080P picture). I'm going to qualify the HD picture as maybe not quite as sharp as DTV EI, but it's close enough for me.
The ONLY thing MLB.com is missing is the ability to watch my home team (Mariners) although the way they're playing recently maybe that's a blessing! No, I realize EI also blacks out my home team, BUT if my RSN (Foxsports NW) is doing the game, I CAN watch the Mariners either on the EI feed or directly from my RSN. This doesn't impact me a bit as my RSN is on my DTV feed anyway, but I have to be tied to my home to watch it.
So, MLB is cheaper and provides a lot more viewing options. Works for me.
