UDP vs TCPIP for TouchIN TouchOUT

It seems the difference in implementing UDP vs TCPIP for TouchIN TouchOUT is that the former needs to know about the target destination (IP address and port) while the latter needs to know about the sender (IP address and port).

I’m assuming that UDP is more efficient but having a problem getting to work.
In the linked video you can see the issue in the TouchIN CHOP.
The only way I can stop the channels from cycling is to pause the timeline in the sending .toe instance.
What am I doing wrong?

Seems like something to do with timeslicing and multiple samples on the sending end generating new channels from samples, can you post that file? Are you sending a moving or timesliced multisample CHOP into the TouchOut?
