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).
