Reply from Philips today:-

Dear Mr. Crowe,

Recently you have asked us why about 70% of your EPG entries are lost.

The reason for this is that there is a problem with the EPG server. We are aware of it, and will do our best to restore it as soon as possible, to get the EPG working the way it should. The problem is fully server related and has nothing to do with your iPronto or it's settings.

We hope we answered your question satisfactorily.

With kindest regards,
Vincent Pfeil
