[streaming] cropping the result of encoded video; eliminate VBI

I am VLC streaming some broadcast video on our campus, which is encoded 
via Hauppaugue cards.  when I view the resulting video using VLC client, 
the VBI is displayed as the top 24 rows, which appears as a fuzzy blue 
line at the top of the video.  note: in analog television systems the 
vertical blanking interval can be used to carry data, since anything 
sent during the VBI would naturally not be displayed.

since the video being received by VLC is already encoded,  is there a 
standard way to receive video from the Hauppaugue card, and strip off 
the VBI data (from the server) so the resulting video displayed on the 
client does not have this fuzzy blue line on top?

thanks in advance :-)
