if you have MLB EI from DirecTV , MLB.TV authentication is working now . i just tested it and able to watch games. so you should be able to watch those teams online (as long as its not your local team )
if your are a 4K fan in the Denver market and missing your 4K sports, please let Altitude know you want your 4K sports back

Might vary based on where you live /local blackouts
If Dodgers or Red Sox play Os or Nats im.blackout but I get all other Dodgers and red Sox 4k games no problem via sat.
It was also said that since D* streaming does not offer mlb EI is the reason why its local/in market only (source...
I added Stream to the 4K chart (sticky post)
according to users on other forums 4K sports are "in market" only.
which is different from SAT, with SAT if you have MLB EI you get Red Sox and Dodgers 4K games
