I'm stumped. It is clear from those traces that the DHCP transaction is working fine. The Receiver gets it's correct IP address and netmask.

For some reason that I can't fathom the Receiver never does the UDP broadcast to find the server.

The only other thing I can suggest trying is to turn off both DHCP servers, add an extra IP address to the PC in the 169.254.x.x range and let the Receiver fallback to pnp to set it's IP address. I doubt this is likely tom make any difference though.

Hopefully Roger can suggest something more useful. It's hard to imagine how this could be a hardware problem given that the Receiver is clearly functioning and talking to the network.
