Wireshark-users: [Wireshark-users] This log doesn't seem right (newbie question)

I am new to using Ethereal/Wireshark, and I am trying to evaluate a TFTP transfer that is taking place over a mesh connection. I have a capture from each side of the transfer, and I have pasted the first few blocks from each below.
I am trying to figure out, is there something wrong in the transfer, or in my capture, or is nothing wrong at all and this somehow makes sense. I used Ethereal 0.99.0 to take the capture (I only just now figured out the name change)
