hi everyone,=0A=0Ai'm trying out kbtv on my shiny new 6.2-release of last w=
eek, but i can't get it to get any display.=0A=0Ato my pleasant surprise th=
e maintainer of kbtv has resumed development a few days ago and released a =
new version 1.2 of kbtv. also with that one, i can't get any channel (prev=
iously i tried with vs 1.1.3). so i was wondering where things go wrong: e=
ither the tuner or the chip to receive images.=0A=0Aconcerning the tuner, =
i built the tools under kbtvs support directory and the tune_channels seem =
to work correctly: the ioctls performing I2CSTART, I2CSTOP, I2CREAD and I2C=
WRITE exit all with 0, so i assume this is working like it should:=0A=0Aioc=
