Why isn't Winter Ball on TV or the Net?

With the 100+ sports channels I have on my directv, NONE of them have room for winter ball from the Dominican or Mexico or PR?  Is there someplace to watch winterleague ball and tide me over in that dark period between the end of the AFL and the start of spring training? If there isn't I really hope this is the type of gap that the new mlb tv network will fill. You can't tell me that Dominican ball wouldnt get better ratings then hlaf the stuff that is on all of those regional sports networks.
