Hi

I've got a problem with EPG web-browser. The best way to overview "what's on now" is to sort it by start time.
It works fine until I there're no fake EPG entries, showing "No program for now", which start at 00:00:00 and end at 23:59:59

And obviously they always are on top.

Is there a way to filter out these epg entries?

I know that there's a duration filter, but:
1) you cannot make "everything, shorter than 8hours"
2) you cannot have it set by default.
