Just installed Wireshark and started capture. Plugged in our GigE camera
under development.  Connected and collected a frame of data.

Wireshark shows all of the GVCP requests and answers.  Very nice!  But I
am not seeing any of the UDP data.  I have no filters set, just selected
the interface then slicked start. I have run Wireshark before on another
computer where the UDP data just showed up along with the GVCP packets.
I know the data is there because my PC app displays the image. But not
in Wireshark.

How do I get the UDP data?

I'm not sure I understand.
It appears that GVCP is carried over UDP so it sounds like you are saying that only certain UDP frames are missing. 

Is the "data" carried over the GVCP protocol ?
If so, I would expect the data show up as being under the GVCP layer of the protocol tree (as opposed to the frames just showing as UDP. 
IOW: the "protocol" column would show GVCP as opposed to UDP.

(I've no knowledge of the GVCP protocol so I may be off-base).
