MLB.TV debuted on Internet connected Samsung TV or Blu-ray Disc™ Players in October 2010.
May 5, 2011 Update: We have confirmed that some blu-ray devices and TVs have audio drop outs and freezes for some users. We are working with Samsung to determine if a firmware update will fix the problem or if there is an insurmountable hardware limitation.
