Hi martin, thanks for your help. > have you installed femon? Have you had a look at the perception level? What > does it say? I have it installed, and this is the output: First without specific tuning to any channel vdr:~# femon -a 0 using '/dev/dvb/adapter0/frontend0' FE: Samsung S5H1420 DVB-S (SAT) status 1f | signal b9b9 | snr b7f6 | ber 00000000 | unc 00000000 | FE_HAS_LOCK status 1f | signal baba | snr b7f6 | ber 00000000 | unc 00000000 | FE_HAS_LOCK status 1f | signal baba | snr b7f6 | ber 00000000 | unc 00000000 | FE_HAS_LOCK status 1f | signal b9b9 | snr b7f6 | ber 00000000 | unc 00000000 | FE_HAS_LOCK vdr:~# femon -a 1 using '/dev/dvb/adapter1/frontend0' FE: Samsung S5H1420 DVB-S (SAT) status 1f | signal bebe | snr b7fc | ber 00000000 | unc 00000000 | FE_HAS_LOCK status 1f | signal bebe | snr b7fc | ber 00000000 | unc 00000000 | FE_HAS_LOCK status 1f | signal bebe | snr b7fc | ber 00000000 | unc 00000000 | FE_HAS_LOCK status 1f | signal bebe | snr b7fc | ber 00000000 | unc 00000000 | FE_HAS_LOCK vdr:~# femon -a 2 using '/dev/dvb/adapter2/frontend0' FE: Samsung S5H1420 DVB-S (SAT) status 1f | signal b7b7 | snr b7fa | ber 00000000 | unc 00000000 | FE_HAS_LOCK status 1f | signal b7b7 | snr b7fa | ber 00000000 | unc 00000000 | FE_HAS_LOCK status 1f | signal b7b7 | snr b7fa | ber 00000000 | unc 00000000 | FE_HAS_LOCK status 1f | signal b8b8 | snr b7fa | ber 00000000 | unc 00000000 | FE_HAS_LOCK And now I switch on VLC to ARD, and receive this: vdr:~# femon -a 2 using '/dev/dvb/adapter2/frontend0' FE: Samsung S5H1420 DVB-S (SAT) status 1f | signal b6b6 | snr b7f0 | ber 00000000 | unc 00000000 | FE_HAS_LOCK status 1f | signal b5b5 | snr b7f0 | ber 00000000 | unc 00000000 | FE_HAS_LOCK status 1f | signal b6b6 | snr b7f0 | ber 00000000 | unc 00000000 | 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 status 1f | signal bbbb | snr b7f7 | ber 00000000 | unc 00000000 | FE_HAS_LOCK 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. > Is there a difference when tuning to SAT.1 (which is on the > same stream like Pro7). SAT.1, RTL and Pro7 look good, all the time. > One other thing that comes to my mind: Sat1 and Pro7 use 7.5MBit/s whereas > ARD, ZDF and stuff use 15MBit, which can be a problem on poor network > performance. 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 streamdev-server a lot, over my 802.11g WLAN .. with VLC on Vista > already. I use it, to watch TV in my bedroom. 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 :-) -- Best regards Peer Oliver Schmidt PGP Key ID: 0x83E1C2EA
