If tvtime is working then I guess it is not setting the format as it
clearly isn't working.
I would try different formats,
# v4l2-ctl --set-fmt-video=width=640,height=480
works for me as well
and then set freevo's geometry to the best setting.
look at the tv/v4l2.py at the end are some test cases which you can run
with freevo execute /path/to/tv/v4l2.py. May be you can hack this file
enough to get this card working.
