it sounds like vic defaults to using the lml board to capture
video rather than the wintv card.  since only one application
can have the lml board open at a time, that would cause rtptv
to fail (although rtptv should give you an error message
about this...)

anyway, in vic, go to the main control window, click on "Device..."
and select the wintv card (it may show up as bttv or something)
and then begin transmitting.  vic used to have a -D argument to
select the default device although that seems to have been
broken, for now you ought to be able to use soemthing like:

  vic -X defaultDevice=v4l1 ...
