AW: [vdr] Problems receiving couple of german channels DVB-S
Okay, we need to put then an eye on your hardware setup - this is a problem before the DVB-S cards. You where talking about 3 DVB-S cards, but how many LNB's do you have? How have you wired the system? We have: horizontal / vertical polarization and then lower and upper band! This makes 2x2 = 4 possible areas. So, if you go with more than 2 cards - 3 or 4 or more, you need a quad LNB with maybe some additional hardware.

Receiving other channels (SAT.1, RTL, Pro7, Das Vierte) works just fine. I've tried using szap to see if I can find the problem in one of my DVB-S cards. Unfortunately, no matter which card I use, I have bad reception for a couple of channels, and good reception for others. Here is an excerpt from the szap log: Bad reception (ZDF): vdr:~# szap -a 0 -n 2 reading channels from file '/root/.szap/channels.conf' zapping to 2 'ZDF': sat 0, frequency = 11954 MHz H, symbolrate 2750, vpid = 0x006e, apid = 0x0078 using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0' status 00 | signal b9b9 | snr fffe | ber 0003 | unc 0003 | status 01 | signal b9b9 | snr fffe | ber 0003 | unc 0003 | status 00 | signal b9b9 | snr fffe | ber 0003 | unc 0003 | status 1f | signal b9b9 | snr fffe | ber e668 | unc e668 | FE_HAS_LOCK status 1f | signal baba | snr fffe | ber 000c | unc 000c | FE_HAS_LOCK status 1f | signal b9b9 | snr fffe | ber 000b | unc 000b | FE_HAS_LOCK status 1f | signal b9b9 | snr fffe | ber 001d | unc 001d | FE_HAS_LOCK status 1f | signal b9b9 | snr fffe | ber 0021 | unc 0021 | FE_HAS_LOCK Good reception (RTL): vdr:~# szap -a 0 -n 5 reading channels from file '/root/.szap/channels.conf' zapping to 5 'RTL': sat 0, frequency = 12188 MHz H, symbolrate 2750, vpid = 0x00a3, apid = 0x0068 using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0' status 01 | signal b8b8 | snr fffe | ber 001a | unc 001a | status 1f | signal b7b7 | snr fffe | ber | unc | FE_HAS_LOCK status 1f | signal b9b9 | snr fffe | ber | unc | FE_HAS_LOCK status 1f | signal b8b8 | snr fffe | ber | unc | FE_HAS_LOCK status 1f | signal b9b9 | snr fffe | ber | unc | FE_HAS_LOCK status 1f | signal b9b9 | snr fffe | ber | unc | FE_HAS_LOCK The interrupts: vdr:~# cat /proc/interrupts CPU0 0: 2373754725IO-APIC-edge timer 1: 9IO-APIC-edge i8042 8: 1IO-APIC-edge rtc 9: 0 IO-APIC-level acpi 14:4835536IO-APIC-edge ide0 15:219IO-APIC-edge ide1 50: 0 IO-APIC-level ohci_hcd:usb1 58: 0 IO-APIC-level ehci_hcd:usb2 66: 441811465 IO-APIC-level eth0 217: 298617322 IO-APIC-level saa7146 (0) 225: 265391314 IO-APIC-level saa7146 (1) 233: 271195814 IO-APIC-level saa7146 (2) NMI: 0 LOC: 2373832282 ERR: 0 MIS: 0 lshw Information for one of the cards (all identical): *-multimedia:0 description: Multimedia controller product: SAA7146 vendor: Philips Semiconductors physical id: 6 bus info: [EMAIL PROTECTED]:06.0 version: 01 width: 32 bits clock: 33MHz capabilities: bus_master configuration: driver=budget dvb resources: iomemory:da00-da0001ff irq:217 Any and help is greatly appreciated. -- Best regards Peer Oliver Schmidt PGP Key ID: 0x83E1C2EA ___ vdr mailing list vdr@linuxtv.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/vdr ___ vdr mailing list vdr@linuxtv.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/vdr

Okay .. but you still can reduce your system down to one DVB-S card .. So, what do you plan to prove that your multiswitch is not broken? What do you do to doublecheck, that your sat dish is correctly set up? -Ursprüngliche Nachricht- Von: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Im Auftrag von Peer Oliver Schmidt Gesendet: Montag, 29.

We eliminate everything that might cause some interaction problem. Get rid of any multiswitch - so just one LNB directly connected to one DVB-S card. No other card in the system. Do you still see the problems? IIRC, unfortunately, this won't work, as far as I understand the LNB. It is one of those 4-connector (I never know whether these are the Quad LNBs or Quattro LNBs) LNBs that NEEDS a multiswitch. Or is my knowledge wrong on the above? And BTW: kyrill moved my SAT dish .. so, why are you sure, that your dish is rocket solid? We have had the problems for a long time ... :-) -- Best regards Peer Oliver Schmidt the internet company PGP Key ID: 0x83E1C2EA ___ vdr mailing list vdr@linuxtv.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/vdr ___ vdr mailing list vdr@linuxtv.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/vdr

Any obstacles in the way, like trees or so? There is something thats called Fresnel zone, which can be painful. Any oscillating frequencies in your PC that may interfere the ~1GHz ZF signal? -Ursprüngliche Nachricht- Von: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Im Auftrag von Peer Oliver Schmidt Gesendet: Montag, 29.

I guess one day, I will have to buy you a beer or two :-) http://www.flysat.com/astra19.php Pro7, Sat1 comes Vertical ZDF,ARD,RTL comes horizontal. If this is a pattern, can it be that you LNB is twisted? So H/V is not perfectly set up? Unfortunately, this is not the case. As written in one of my many messages, EinsPlus can be received without a problem. And if I understand the information in the channels.conf correct, it comes Horizontal as well. And RTL is looking good as well ...

Hi Peer Oliver, can you give us a hint what the problem is? So if you only have budget cards, what kind of frontend do you use? Need to know a bit more from your setup.

Receiving other channels (SAT.1, RTL, Pro7, Das Vierte) works just fine. I have three budget TT cards connected to a multiswitch in my attic, just a few meters cable away from my dish. Each DVB-S card is running on a different IRQ. Is it possible, I just miswired the multiswitch? Any idea on how to fix this problem would be greatly appreciated. -- Best regards Peer Oliver Schmidt PGP Key ID: 0x83E1C2EA ___ vdr mailing list vdr@linuxtv.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/vdr ___ vdr mailing list vdr@linuxtv.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/vdr

Hello martin, can you give us a hint what the problem is? So if you only have budget cards, what kind of frontend do you use? Need to know a bit more from your setup. Sorry for not being more verbose. I am using streamdev-server on the VDR in the attic, and VLC as a frontend running downstairs on a WinXP or Ubuntu system. The problem is a totally distorted picture, like when I have thunderstorm outside with bad reception. Block artefacts etc. Sometimes it gets so bad, VLC quits from errors. The funny thing is, it is ONLY on some of the channels. -- Mit freundlichen Grüßen Peer Oliver Schmidt the internet company PGP Key ID: 0x83E1C2EA ___ vdr mailing list vdr@linuxtv.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/vdr

Hi Oli, have you installed femon? Have you had a look at the perception level? What does it say? Is there a difference when tuning to SAT.1 (which is on the same stream like Pro7). 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 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.

Hi, there is a plugin Femon available - much nicer output! You should check it out! Then you have clear text messages. So, I'm no expert, but ber and unc must be zero (I'm sure you can have a look in wiki). So, as you see, you had some values there. This seems then to be a signal problem. Either your sat dish is not perfectly set up or you may have problems with v/h switching. Btw: I use femon plugin in vdr to adjust my dish. So how did you do?

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?
