Can you give some advices on how to tune AverMedia 507 to given frequency? I've no other OSes on this machine.
I've used saa driver from your kbtv-1.1.1 tarball. Changed
lines in Makevars are:
TUNER_FLAGS+= -DTUNER_WR_I2CADDR=0xc2 -DTUNER_RD_I2CADDR=0xc3
after loading the driver:
saa0: <Phillips SAA7133 AV broadcast decoder> mem 0xf6004000-0xf60047ff
irq 19 at device 7.0 on pci1 pcib1: saa0 requested memory range
iicbus0: <SAA713x I2C Controller> on saa0
iic0: <I2C generic I/O> on iicbus0
saa0 at pci1:7:0: class=0x048000 card=0x97151461 chip=0x71331131 rev=0xd1
vendor = 'Philips Semiconductors'
device = 'SAA7135HL Multi Media Capture Device'
class = multimedia
But tune_channels can't find any channel, set_channel /dev/iic0
<anyfreq> and running tvv shows only black window.
