The first thing that comes to mind is how does your video capture 
device work in other programs?  If other apps don't give a satisfactory 
picture then it's most likely a driver issue or perhaps even faulty 
hardware.  Otherwise, if only GEM is giving poor results then pix_video 
is either using the video API incorrectly or just using the wrong one 
to begin with.  Can you post a screenshot of the video you are getting 
right now and also the patch?

In my limited Windows video capture experience, I found that XP has the 
most drivers available now for consumer level cards.  Which device are 
you using?  Most boards actually use one of a few available chips to do 
the digitizing and the drivers for the common ones are definitely out 
there for XP.

The video device driver also has to link into a Windows API, and the 
current CVS version of GEM has a Microsoft DirectShow compatible 
pix_video which should support a wide range of devices.  Here's a build 
that should have this object included:
