On a single card system it doesn't really make much sense to have
shorter times - after all, you wouldn't even be able to watch a full
length movie.

Besides, if you want to start an EPG scan you can select "Scan" from the
Setup/EPG menu at any time.

This may be a dummy channel that's used to tune to a new transponder.
It doesn't have a number.

Well, since there is a patch involved that may well interfere with all
this I'd say you should test without that patch first and see if it
happens there, too.
