I have more than one card ;-)
But somewhere i read the EPG infos are mostly changed only 
between 2:00 and 3:00.

Ah, i see.
I thought EPG scan would only occur after a lengthly "idle" time
and "politely" switch away the channels when no user is present. 
(If i am already sleeping it would be a feature if VDR would wake 
me up by switching the channel. ;-))

I would not expect such a function under "Setup", more under "Commands"-
but anyway:
Under "Setup/EPG": I have only a line named 
"EPG scan timeout(h):   0"
"EPG bugfis level: 2
"EPG linger time(min): 90"
"Set Systemtime: yes"
"Use time...
But no "EPG scan now!"
(because i have more than one card?)

Ok, it makes no trouble. just interessting to know.thanks.

I can't test it because the box is normally turned off.
An i don't understand why the EPG scan switches to channel 279 
and not to channel 3.

Too i really don't think that the patch could cause that loop.
The message was not "locked by LNB", as no recording was running,
but simply "Channel not available" because is needs a CA.

That patch existential for my box.
With out it EPG scan would switch to a not allowed 
polarization, given "video stream broken" panic bye bye.

I never had the problem before (but
a) the box never idles so long 
b) EPG was of because of history reasons

Maybe we should first ask, why it is switching to channel 279?
Why does EPG do not react to the error code but insists on
switching to 279?
I assume no one was at home and press 279 on the Rc.
And if, it should not lead to a loop (and does not
