[AG-TECH] Winnov Videum Quattro

i've run into similar problems multiple times with the 4400 VO.  it usually
happens when i switch to a different style of VideoProducerService
(e.g., JPEG, MPEG4), but it sometimes occures for other reasons.
one potential fix is to right-click the VideoProducerServics from within
the same menu that you added them to your configuration.  select configure
and make sure that they are properly set.  sometimes they aren't.

if that doesn't fix it:
if you are using a windows box for transmission,
here's what you might try.  it's worked for me in the past, to a point...
open the configure option in the vics that are blank.
on the first "options" dropdown on the left of the GUI, select
configure on transmit.  then go select 'release' at the top followed by
re-selecting 'transmit'.  this get's you into some lower-level GUIs.  by
selecting the video stream in this menu, i've often been able to get the
VIC to transmit correctly.  the upside-down issue is because, for
some reason that i don't understand, your VIC transmission is not set
to h.261.  in this same menu, if you re-set it to h.261 it will not only
get rid of the boarder, but it will transmit the image rightsideup.
saving these configuration options is another story.... good luck on that
