I found it never worked (in 2 or 3 trials...). I should really disable
it and wait for when/if a firmware update is ever available.

Sliced VBI as a separate stream, for NTSC at least, should be working
without a hitch now. Although there is no interlock for the driver
trying to stuff ivt0 private streams into a TS as if it were a PS, so
don't turn on sliced VBI insertion into the MPEG stream unless you're
using a PS.

I didn't remove them. I don't see them showing up though either in
v42l-ctl -L . However, there is code in cx2341x.c for setting and
getting the controls, and v4l2-ctl --log-status logs their state. Does
ivtv show them? I looked at the 'hg log -vp cx2341x.c ' output and
could see where the queries were ever removed in recent history.

Add it to the todo list. *sigh*

No.

There's no harm in trying. I just recall it not working for my very few
trials.

Correcting a typo: 'and I could *not* see where the queries were ever
removed'
