Hi! I just got myself a Sensoray Model 611 frame grabber (bt878) and I'm having trouble making it work under Linux. I'm running Red Hat 8.0 which already has the bttv driver (version 0.7.91) installed as a module. When I plugged the card, it was detected by Red Had and it added the following line to my /etc/modules.conf : alias char-major-81 bttv I tryed to capture some images (using several programs) but I cant get a clear image, all I can see is some vertical and horizontal stripes. I live in Europe, so my cameras are PAL. I've tryed both in PAL (768x576) and NTSC (640x480) with the same results. Ive been looking on the internet, reading online forums, but I can't still make it work. I've tryed the following /etc/modules.conf, but the image is still the same: alias char-major-89 i2c-dev options i2c-core i2c_debug=1 options i2c-algo-bit bit_test=1 alias char-major-81 videodev alias char-major-81-0 bttv options bttv card=0 options bttv pll=1 When I type: modprobe bttv the following log is written to /var/log/messages: Oct 29 23:33:42 localhost kernel: Linux video capture interface: v1.00 Oct 29 23:33:42 localhost kernel: i2c-core.o: i2c core module Oct 29 23:33:42 localhost kernel: i2c-algo-bit.o: i2c bit algorithm module Oct 29 23:33:42 localhost kernel: bttv: driver version 0.7.91 loaded Oct 29 23:33:42 localhost kernel: bttv: using 2 buffers with 2080k (4160k total) for capture Oct 29 23:33:42 localhost kernel: bttv: Host bridge is Silicon Integrated Systems [SiS] 630 Host Oct 29 23:33:42 localhost kernel: bttv: Bt8xx card found (0).
