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.

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.

Does anybody knows something new about the card? I still do not find anything usefull and the card is still not working.

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.
