Sorry to dig up an old thread, but this seems to be not working again in the System plugin (I don't think it's 2.6.2...I think it's been broken for a wee while).
After an EPG update, the top-bar in the EPG shows recordings marked, but the actual programmes have no highlight. An exit/reload of NPVR makes them appear again.
Here's a shorthand of what I have it doing:
Code:
new EPGManager().UpdateEPG(this);
ExportImport.ExportRecordings(false);
// EventBus.GetInstance().Notify("RELOAD_RECORDINGS");
EventBus.GetInstance().Notify("RELOAD_SETTINGS");
