When you say that you tried CMU's DCAM to no avail, specifically what do 
you mean?  Did it fail to work with the CMU demo program or just with 
MATLAB.  Also, what version of the CMU drivers were you using?  It is 
possible that the camera is not DCAM compliant.

However, when using the WDM or VFW drivers, how did the image look using 
the AMCAP utility?

Also, what is the output that that you see if you create the winvideo 
object and then do the following:

% modify the line below as needed for your desired format and device
vid=videoinput('winvideo')
% and then...
start(vid);
d=getdata(vid);
f10=d(:,:,:,10);
max(max(f10))
min(min(f10))

Can you send me the answers to the above questions as well as the output 
of the above commands?  It would also be good to see the output from the 
IMAQSUPPORT command.

Thank you,
Mark
