You can pay for it through mlb.tv, a 100 buck a year for the every single game is not bad at all. I assume you are looking for a free option too. The premium package for $120.00 gives you DVR controls. If you know anyone else who wants this option you can split the cost, I believe you can login at the same time.
if you really want then you can pay for it and enjoy for years.i think its good package and you should go through it if u really serious about it. you can also share your burden if you know anybody else who is also interested.
