Hugo,
I've tried your setting, but now i don't have tv at all.
All i can see is some snow with image shadows.
How can i remove this ???
It must be in:
/usr/bin/ivtvctl -d /dev/video0 -u 0xff
/usr/bin/ivtvctl -d /dev/video0 -p 4
/usr/bin/ivtvctl -d /dev/video0 -f width=720,height=576
/usr/bin/ivtvctl -d /dev/video0 -c dnr_mode=0
/usr/bin/ivtvctl -d /dev/video0 -c dnr_temporal=0
/usr/bin/ivtvctl -d /dev/video0 -c dnr_spatial=0
Because these settings i had already this which gave no problems.
/usr/bin/ivtvctl -j reg=0x6c,val=0xfa -d /dev/video16
/usr/bin/ivtvctl -j reg=0x2d,val=0x38 -d /dev/video16
Please help !!!
Patrick

For PAL tuners this might help you out:
/usr/bin/ivtvctl -d /dev/video0 -u 0xff
/usr/bin/ivtvctl -d /dev/video0 -p 4
/usr/bin/ivtvctl -d /dev/video0 -f width=720,height=576 /usr/bin/ivtvctl -d
/dev/video0 -c dnr_mode=0 /usr/bin/ivtvctl -d /dev/video0 -c dnr_temporal=0
/usr/bin/ivtvctl -d /dev/video0 -c dnr_spatial=0 /usr/bin/ivtvctl -j
reg=0x6c,val=0xfa -d /dev/video16 /usr/bin/ivtvctl -j reg=0x2d,val=0x38 -d
/dev/video16
It gives me a rather good image.
Mind you video16 is the OUTPUT device and video0 the INPUT device.
(hence to watch TV you may use: dd if=/dev/video0 of=/dev/video16 bs=64k &)
