I recently decided to bite the bullet and upgrade from a practically new Premiere 4 to a Roamio Plus. Today I thought I'd watch an archived baseball game using the MLB.TV app. It didn't work. Well, after 2 calls to TiVo and one to MLB.TV I found out that MLB.TV is not supported on the Roamio (even though it is listed as a video provider in settings/channels). It is supported on the Premieres but not the Roamios! I just can't believe that I spent the money on the Roamio and lost some functionality. The second TiVo rep I spoke to told me she would submit a feature request to have this added but could give me no assurances that this would happen any time soon. If there are any other baseball fans out there, please call TiVo and request that they add MLB.TV functionality to the Roamio line.
