Hi Gerd,
Do you have a view about this problem? In my code I disabled this code:

And bttv will not stay on the composite input through attempts to mute and
unmute. Of course, muting no longer does anything - but that's OK for me.
Do you agree its a bttv v4l2 bug? (does affect xawtv too when it uses the
v4l2 interface.
Thanks,
