Hi martin,

thanks for your help.

I have it installed, and this is the output:

First without specific tuning to any channel

And now I switch on VLC to ARD, and receive this:


vdr:~# femon -a 2
using '/dev/dvb/adapter2/frontend0'

FE_HAS_LOCK

vdr:~# femon -a 1
using '/dev/dvb/adapter1/frontend0'
FE: Samsung S5H1420 DVB-S (SAT)
status 1f | signal bbbb | snr b7f7 | ber 00000000 | unc 00000000 |

FE_HAS_LOCK

vdr:~# femon -a 0
using '/dev/dvb/adapter0/frontend0'
FE: Samsung S5H1420 DVB-S (SAT)
status 1f | signal baba | snr b7f0 | ber 00000042 | unc 00000042 | 
FE_HAS_LOCK
status 1f | signal bbbb | snr b7f0 | ber 00000000 | unc 00000000 | 
FE_HAS_LOCK
status 1f | signal bbbb | snr b7f0 | ber 00000000 | unc 00000000 | 
FE_HAS_LOCK

To me, I see a difference within the signal. But unfortunately, I can't 
interpret the message.

SAT.1, RTL and Pro7 look good, all the time.

I have the ASTRA.HD channel running right now in the background 
(S19.2E-1-1088-21101) and it works perfect. Input-Bitrare according to 
VLC is ~ 19MBit.

I also use VOMP to connect Hauppauge MediaMVPs and they have the same 
problem with those channels. Do you know anything else, that ARD + ZDF 
have in common, that is different from Pro7 and RTL? Is it possible, I 
have plugged the cables wrong into the Multiswitch?

Thanks for your help on a sunday afternoon :-)
