Is the EPG function still running? My Tivo hasn't had guide data for several days, and I'm wondering if it's a problem with my Tivo or the system.
The guide is currently working fine and my TiVos have EPG data cached until Saturday 9th February, with the last successful connection that was yesterday. That's exactly what should be there.
I suggest you do a manual network call and watch what's happening from the status messages.
When I do that, the second step (Connecting) halts with the error "Failed while negotiating". I've tried restarting the Tivo, and the error is still there. The Network Diagnostics "Tivo Service connection" passes. Is there somewhere else on the box that will give me more detail?
