crgauth's link is probably OK for the list of Samsung TV models but the BluRay list is not correct - pretty much all there are NOT supported - yet. I have a BD-E5900 and it is NOT supported. Someone did post that they had a BD-D5300 (in another thread) and the app was available for and worked on it.
Samsung said they had no ETA on when the players (in particular, the BD-E5900) would be good to go.
Also, in another thread, someone posted that the LG BP620 BluRay did run the FiOS app. -- Never raise your hands to your kids. It leaves your groin unprotected. -- Red Buttons
