It is at: http://linuxtv.org/hg/~hhackmann/v4l-dvb It does compile on kernel 2.6.20, i have it running here. Just to be sure: - if you compiled for another kernel before, you need to delete the file v4l/.version - don't try to merge the files into the kernel, compile them separately with make, make install (for the install, you need to be root - never mix modules with older versions. - afik, you need to enable the v4l and dvb stuff in the kernel tree. Looks like you missed a mail from me, i will just paste it here: I had a look at the eeprom dump again: The card should be a copy of the Tiger-S reference design without radio. So please try this: Get a copy of my personal repository, compile and install. Then do: modprobe saa7134 card=109 secam=l modprobe saa7134-alsa modprobe saa7134-dvb This should do it as long as there are not tricks with the windows driver. You sould no longer need to load the saa7134-alsa and saa7134-dvb modules manually. Good luck Hartmut _______________________________________________ linux-dvb mailing list linux-dvb@xxxxxxxxxxx http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb
