I view Verizon FIOS TV via a Verizon CableCard and Windows Media Center
The Pittsburgh FIOS (digital) headend was changed on or about June 2, 2013
This stops access of the Guide Data.
You see this in the "Event Viewer" "Applications and Services Logs" "Media Center"
(find Event Viewer from Start Button search for event)
The event message contains ... Failed to retrieve EpgListings (Error: HeadendId 177570243 is invalid.)
To align with the new FIOS headend. Run the Windows Media Center TV Signal Setup again
Green Button | Tasks | Settings | TV | TV Signal | Setup TV Signal
It would be helpful for Verizon FIOS to send a message to CableCard customers when they change the FIOS headend so they can realign with the new headend before they lose the Guide data.
