  Thanks a lot for your tip, but I tried tvtime already. It just gives me a blue window with the text it cannot find /dev/video0. I checked it and this device does not exist. Unfortunately there is no device at all that looks like a TV card. I think the saa7231 driver is not installed or loaded correctly. My problem is, that I do not understand how to use this driver.

  it seems that i have the same problem =(
  
  driver from http://www.jusst.de/hg/saa7231/ fails to compile:
  
  *** No rule to make target `/root/saa7231-c6048b34be66/v4l/saa7231_pci.o', needed by `/root/saa7231-c6048b34be66/v4l/tda18271.o'. Stop.
  
  system:
  slackware 13.0 x86_64 kernel: 2.6.32.2

  I also got this error message. I could avoid it by using make -i instead of make all, but I do not think that this makes any sense because the driver didn't work either.

  make -i make gcc to ignore errors which doesnt help cause the error is in saa7231,....
  
  it looks like there are missing some files ( saa7231_avis.h, saa7231_avis_req.h )
  
  i tried to remove those files,...
  which made it compile without errors but the the module dint load into kernel =(

  Hi Martin,
  
  how did you identify those two files (saa7231_avis.h, saa7231_avis_req.h)? I thought that the file saa7231_pci.o (or the related c or h file) is missing.
  
  Regards,

  Hi,
  
  I wrote the developers of the driver a few days ago and they told me, that the driver is not ready for usage now. The work is still in progress and it needs some more time till we can use the code.
  
  Regards,
  
  Michael

  I contacted Trident Microsystems, now owner of the SAA7231 (NXP sold it off), and they flat out refused to give out any information on this chip to Linux developers. I asked them to reconsider, and they came back a day later with the same result.
  
  So Trident Microsystems has a clear "No Linux" policy in place for the SAA7231. That's it. Linux support won't happen. The SAA7231 is for the trashcan, as is any TV card with this chip on it. That's the manufacturer's will.

  Thank you very much for this information. It is sad to hear, that the manufacturer does not like Linux. So I have to look for a new TC card.
  But thanks again four your help.

  If any developers are interested in trying to develop drivers for this manufacturer's cards, I recently found that the Linux Foundation has an NDS program (http://www.linuxfoundation.org/programs/developer/nda) which will help negotiate NDA agreements to facilitate development of open source drivers for proprietary hardware.
