Ulf,
Some progress with my NTSC (tuner=50) PVR-150 and your latest patch:
With mixer_input=2 and 'ivtvctl -p 2' (composite) I get perfect composite
video and audio.
With mixer_input=1 and 'ivtvctl -p 6' (NTSC) I get tuner video and no audio.
With mixer_input=1 and 'ivtvctl -p 2' (composite) I get composite video with
tuner audio.
Still no audio and just grey screen with any mixer_input and 'ivtvctl -p 0'
(S-video) input.
Hope these clues help.
Thanks,
Jim
