go to a TV Live channel (use channel 365 Sky Comedy for this), and then hit the GUIDE function on the remote.
An EPG menu will appear. Let it sit there a couple seconds. The EPG may populate then.. If not let it sit there for a couple minutes and see what happens.
If anything appears, then scroll to the right and then again let it sit for a few seconds.
Vixo1 EPG info works for the expected channels that now have EPG info, about half the channels or so should show the EPG info.
