It's even worse then I thought. The EPG is not only not updating, but the guide dissapears too. Yesterday I had EPG information till Saterday, now it is empty. For testing purposes I had 2 different guides for different channels, to rule out certain causes. But all is empty now. Empty is the mcguide EPG and empty is the EPG got from the DVB-C channels. Updating leaves me with an empty guide.
In the process of reinstalling the BDA drivers again, what seems to be the short term solution (for a few days). That is very annoying.
EDIT: it has to be on the server side of things, all clients behave simular
