I am a DirecTV sub and have subbed to EI through them for the last few years. Next year I think I too may cancel EI and watch MLB.TV through my PS3. This will also allow me to watch it on any computer as well and for less money than EI
Why not just pay $7 for the sports pack. Many games worth watching in the 9th go over the scheudled time, due to either close play or rain delays, and Dish restores the channel. I watched many of Mets games because of these issues. However, this isn't full proof.
