You may need to debug this a bit yourself, it's not too hard. In
tv/v4l2.py add some print statements in the setstd (you can also set
DEBUG=2 in local_conf.py but this will give too much information). When
you see the standard being changed to PAL you can add a couple of lines:
import traceback
traceback.print_stack()
This will show you from where the setstd was called from.
Another trick is to type
freevo prompt
>>> import pprint
>>> import config
>>> pprint.pprint(config.__dict__)
This will show all the configuration settings; to send this to a file use:
>>> f = open('/tmp/x', 'w')
>>> pprint.pprint(config.__dict__, f)
>>> f.close()
grep -i pal /tmp/x
will show you if PAL has been set somewhere.

I think that you should get the correct default just after boot and
before freevo has changed it to PAL. Or by stopping the record server
and freevo and rmmod and modprobe the driver.

It's a bit difficult to default this. I don't think there a way to
default the channel list?
