I wrote Trip and here is his response:
The TVGOS equipment is notoriously unreliable. At this very moment, I have heard there could be two or three separate TVGOS outages, KIRO being one of them, so while I suspect it will be fixed, I can't really offer you a timeframe since I lack the inside information on it.
The local station engineer likely has no control over the situation, as the TVGOS box is usually completely remote controlled by Rovi. The most the local station engineer can do is remove it from the system or reboot it if it locks up.
Your best bet would be to call Rovi, but I'm not sure they will be of much help either, I'm afraid.
I'm sorry I cannot be more helpful, but I do hope your issue is resolved sooner rather than later.
By the way on the Seattle forum someone has posted the TVGOS is back up and running. I have not been home yet to check but maybe someone got tired of all of us whining. Miracles do occasionally happen.
