I'm glad that you found the answer that it is not possible to change the
standard when the device is in use. I can put some code in to show a
warning box.
I may not be possible to change the input too when the device is open.

When a tuner is defined as external then you may need to enable
tv.irsend_generic or tv.irsend_echostar plugins to send the channel
command to the device but since you tuner is not external you don't need
the commands.

Are you sure that you don't need to set the standard when using a
composite or s-video input?
First I would go back a step and try not changing channel this way but
by selecting a channel from the TV guide menu. This way there is no open
device so the input and standard can be set. Getting these to work is
the next step after checking that the v4l2-ctl commands are working for
you card.
Unfortunately, I can't test this for you as I only get PAL. Even though
you don't program it bay be possible that you can add print commands to
the tv/channels.py to see what is going on. Simply add a:
"print 'variable_name', variable" indented at the same level as the
following or preceding line. ie:
| freq = config.TV_FREQUENCY_TABLE.get(chan)
| if freq:
| _debug_('Using custom frequency: chan="%s", freq="%s"' % \
| (chan, freq))
| else:
| clist = tv.freq.CHANLIST.get(vg.tuner_chanlist)
| if clist:
adding prints so.
| freq = config.TV_FREQUENCY_TABLE.get(chan)
> print 'freq', freq
| if freq:
| _debug_('Using custom frequency: chan="%s", freq="%s"' % \
| (chan, freq))
| else:
| clist = tv.freq.CHANLIST.get(vg.tuner_chanlist)
> print clist
| if clist:
You will need to restart freevo to the new version to be used.
But first things first.
1) check the v4l2-ctl commands are setting the channel up correctly
2) use the TV guide to select a program.
3) add print commands to see what is being called and set.
