Hello,

I have a problem using the bt869 module with my voodoo3 3500 and tv-out.

insmod the modules
Using /lib/modules/2.4.20/kernel/drivers/i2c/i2c-voodoo3.o
i2c-voodoo3.o version 2.7.0 (20021208)

bt869.o:  probing address 68 .
bt869.o: address 0x44 testing-->0x22
bt869.o: BT869 detected

bt869.o: write_value(0xC8, 0x0)
----------------
here i can see my console on the tv but it looks bizzar.
i guess its an NTSC-signal
but changing the proc-values leads to an black tv
ether no signal or something else
even cat'ing the values leads to an bt869 update and a black screen
i have tried changing the default values in the drivers to my fits but i 
didnt' work.
unloading the driver und reloading it brings me back to the console to 
the tv which looks bizzar.
