Ever since I had Verizon fios installed, I have been unable to use On Demand (it says that is is disabled and to call verizon). Now the guys who installed fios said that it was just a glitch and it should start working soon...well it's been nearly 2 months and still no on demand. I have no idea why and would really love to be able to use it.
I assume you are getting this on Verizon stb?
