Can I see those five lines? ;-) While you're at it, you may as well include dmesg from the point that the bridge driver loads and on. I don't know how the AF9015 works, but Antti does. What demod is on this device? ...or is that part of the AF9015? After googling some more, I found that the tda18211 supports DVB-T, ATSC and QAM ... Seems to be a digital-only tuner, while the tda18271 supports both digital and analog. The IF frequencies used for the tda18211 are the same as the default settings for the tda18271c1. - QAM: IF output centered at 4 and 5 MHz (bandwidth = 6 and 8 MHz respectively) - DVB-T: IF output centered at 3.3, 3.8 and 4.3 MHz (bandwidth = 6, 7 and 8MHz respectively) - ATSC: IF output centered at 3.25 MHz (bandwidth = 6MHz) ...I am looking at the snoop log some more -- My earlier statement was wrong -- I *do* see the driver programming all 39 registers, and now I do see calibration transactions taking place. I can see from this snoop that the value that belongs in the linux driver's "std_bits" parameter should be 0x19. It looks like the windows driver starts off with 0x18, and after some wiggling, locks at 0x19. Maybe it is first trying to tune to a 7 MHz DVB-T channel, then changes to 8 MHz. You said that you tuned to "channel 7, sydney, australia" -- is that an 8 MHz channel? What frequency is it on? -Mike _______________________________________________ linux-dvb mailing list linux-dvb@xxxxxxxxxxx http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb
