SOme people have experienced problems.
They way it is supposed to work is you go in to FIOS Mobile App.
Go to DVR.
When you select a recording, you are supposed to have option to play.
IF the picture reported is your equipment you have a VMS1100. Normally this means you have Quantum TV service, although some people have a different version of software that limits it two only two of its six tuners. i.e/. non-Quantum TV service.
Those with Quantum TV should be be able to stream anywhere. It should be obvious on your bills.
