Doesn't the driver set the tuner bandwidth based on the frequency? > > the read of register 0x00 returns the same as the read of register 0x7f! > > I don't know what's going on.

Surely this is a fault with the i2c driver? This is what i get when bttv is started: bttv: driver version 0.9.14 loaded bttv: using 8 buffers with 2080k (520 pages) each for capture bttv: Bt8xx card found (0). bttv0: Bt878 (rev 17) at 0000:02:06.0, irq: 17, latency: 64, mmio: 0xea100000 bttv0: detected: AverMedia DVB-T 771 [card=121], PCI subsystem ID is 1461:0771 bttv0: using: AVerMedia AVerTV DVB-T 771 [card=121,autodetected] bttv0: gpio: en=00000000, out=00000000 in=0098008f [init] bttv0: using tuner=-1 bttv0: registered device video0 bttv0: registered device vbi0 bttv0: PLL: 28636363 => 35468950 . ok bttv0: add subdevice "remote0" bttv0: add subdevice "dvb0" I use: bttv i2c_hw=1 to make sure it's using hardware i2c. and I use the modules i2c_core and i2c_algo_bit. I don't know much about the i2c modules, should I be using a different module other than i2c_algo_bit? Is it dependant on the motherboard? Jolse
