Hello,
I have a Terratec Cinergy DVB-S TV card, the modules (dvb-ttpci and others) are correctly loaded by hotplug. So far so good. Yet nothing works (tvtime & kdetv), it can't get a signal.
In the terminal, it says:
videoinput: Cannot open capture device /dev/video0: Keine Berechtigung
rtctimer: Cannot set periodic interval: Keine Berechtigung
("Keine Berechtigung" meaning "No permission")
When I look at /dev, I see that there is no video directory, nor a v4l.
I looked through these Forums but can't find anything useful.
Further specs:
1. v4l loaded in xorg.conf, tv card modules loaded
2. udev instead of devfs (which works fine everywhere else)
3. user is in video group (which I had to add by myself)
Here are excerpts of my udev-rules file:
# video devices
SUBSYSTEM="video4linux", GROUP="video"
KERNEL="dvb*", PROGRAM="/etc/udev/dvb.sh %k", NAME="%c", GROUP="video"
KERNEL="nvidia*", GROUP="video"
KERNEL="card[0-9]*", NAME="dri/%k", GROUP="video"
# v4l devices
KERNEL="video[0-9]*", NAME="v4l/video%n", SYMLINK="%k", GROUP="video"
KERNEL="radio[0-9]*", NAME="v4l/radio%n", SYMLINK="radio%e", GROUP="video"
KERNEL="vbi[0-9]*", NAME="v4l/vbi%n", SYMLINK="%k", GROUP="video"
KERNEL="vtx[0-9]*", NAME="v4l/vtx%n", SYMLINK="%k", GROUP="video"
I hope you can help me...

Hello,
The thread you mentioned couldn't help me. I don't know what I have to do since I read through all the topics discussed here...
Again, I have "no permission" for the devices in question:
kdetv:
vicd@blackdeath ~]$ kdetv
kdetv: WARNING: [VBIDecoder::restart()] no permission to access device
tvtime:
vicd@blackdeath ~]$ tvtime
Starte tvtime 0.9.15.
rtctimer: Cannot set periodic interval: Keine Berechtigung
Konfiguration des Zeitgebers (RTC) auf 1024 Hz fehlgeschlagen. Diese
hohe Frequenz ist nötig, um ein ruckelfreies Bild zu gewährleisten.
Bitte starten Sie tvtime mit root-Rechten oder erhöhen Sie die maximale
RTC-Auflösung, indem Sie als root folgendes Kommando ausführen:
sysctl -w dev.rtc.max-user-freq=1024
Weitere Informationen finden Sie unter http://tvtime.net/.
Lese Konfiguration aus /etc/tvtime/tvtime.xml
Lese Konfiguration aus /home/vicd/.tvtime/tvtime.xml
videoinput: Cannot open capture device /dev/video0: Datei oder Verzeichnis nicht gefunden
Danke, daß Sie tvtime gewählt haben.
Greets,
Vic

quick hack to test:
chmod the devices to lower security. I have several issues right now with udev and group permissions. Maybe it is udev, that is not doing well. I am not quite sure about the current udev behaviour on my machine, but I found several things not working well. My own ruleset is not setting up groups, while the udev rule is setting groups. I recieve nvidia permission errors while doing some opengl things, althoug I am member of video, 2. Anyway, I never got my cinergy to work, maybe we could help each other out. Feel free to pm me, I will try to follow your steps and see if I get the same results. Tschuess!

Hello, there!
Now it works in Kaffeine at least, but this should be enough! But the quality is very poor, do I have to install accelerated drivers for my Radeon? Or are there codecs (or sth else) that have to be installed? The quality is by far not good enough to watch TV over a more lengthy period of time...

tell me what you did to make it work

Actually, I did not do much, I edited udev.rules according to what has been posted in this thread.
I don't know if the changes I made are the ones that finally made it work, but it could very well be. Kaffeine detects the card without any problems, kdetv and tvtime don't.
But as I said the quality is poor, so it's no fun watching TV like this. If anyone has an idea what to do in order to increase quality (codecs? accelerated drivers?), please tell me.

To get full graphics acceleration for your Radeon card, you can install the ATI drivers. I haven't done it myself. Search the Wiki and forum for more info.
You can also try the following before installing the drivers. It will use DRI for the xorg radeon driver. In xorg.conf:
Add
# This loads the GLX module
Load "glx"
# This loads the DRI module
Load "dri"
to your Modules section.
Add:
Section "DRI"
Mode 0666
EndSection
Add:
Option "RenderAccel" "On"
in the Device section of your monitor.

I can tell the quality is very well using nvidia and kaffeine. I am surprised there where no more necessary steps ... but ... using kaffeine.
