Howto reset EPG database after wakeup from suspend

Hi,

I'm using xbmc frodo with PVR enabled and tvheadend backend. Everything is working nice, but there are problems with EPG data after wakeup from suspend.

After wakeup the EPG data are not correct, sometimes the tv channels are mixed too.

One thing which helps is to reset EPG database or channels. Is there some possibility to do this reset remotely by JSON-RPC or so?

Regards

Tomas
