[AG-TECH] New Fedora Core 2 AGTk CVS snapshot

[Eric Olson]

Hi Fred and Doug,
I checked in a small change to VideoService.py and VideoProducerService.py 
in cvs that should fix the problem causing the video port settings getting 
reset to the default port all the time (Bug #1067).
Let me know if it fixes that problem for you once you're able to test 
it.
