Hope it is not a problem that I'm bringing this old thread back to the top. I recently got Fios again and I can't get MASN to play on Fios Mobile. It only gives me the "Watch on TV" option and my phone is on the same wifi as my set top box. Do you need Extended DVR to get this service? I asked the Fios tech support people but they seem to be clueless.
Check to see that your wireless device is on your FiOS WiFi network. If not, you'll only be able to watch a small amount of channels on your mobile device. Unfortunately this means you can't watch MASN through your phone when you aren't in range of your FiOS WiFi.
