Hi Andrew,
I am using multicast. When I use the already compiled VIC binary (from
the UCL installer), video appears in both VideoConsumerService and
VideoProducerService windows.
The issue occurs when I use a VIC binary I compiled in Visual Studio 8.0.
When using the my compiled VIC, neither window has any video, but it is
transmitting correctly since a remote machine, using a standard VIC
binary, can see the video properly.
I think I've caused bugs in the program when trying to compile VIC in
VS8.0. The following is the debug output:

The error occurs in the "really_activate" procedure, which, according
to this article https://mediatools.cs.ucl.ac.uk/nets/mmedia/wiki/VicDev,
is responsible for creating the video thumbnail.
