Remove messages, of course, to keep things simple I suppose?

The IP-EPG is predominantly a Dutch problem, what is the issue of some messages in Dutch?

Well then again in English:

Ziggo says it is a Philips software issue, and it has NOTHING to do with them controlling EPG info or something like that!

The trick to overcome the issue is to change to DVB-T and use a piece of wire as antenna, reinstall channels, don't just update them. After reinstalling the channels, choose network EPG. You should see the IP EPG by now. Dhange back to DVB-C. Now the IP-EPG should still be available.

The fact that the workaround works implies indeed that it is a Philips software issue, otherwise Ziggo would start blocking IP-EPG directly after reconnecting the coax cable.....
