[vdr] Check for updates of present event

Hi,

I want to check for updates on the present events in the schedule. I was checking "Schedule->Modified > lastModified", where lastModified is the timestamp when I checked it last time. However, every time I do the check, it was modified, even if there's no obvious change.

So, how do I check if the present event (currently running event) was modified, i.e. the current event was replaced by the next event or any detail of this event has been changed?

Additionally, I'd like to know, if there equivalent way to do such a check on the channels list as Channels.Modified() is reset after the call. I have never detected a channel list change though syslog states some automatic changes.

Thanks for any kind of help!
