To reply to my own post, it looks like the problem was caused by an 
unexpected firewall configuration at the client side, and I didn't end 
up having to compare traffic streams. Yet.

Thanks to all for your suggestions. As a side note, I discovered a 
feature in Ethereal I hadn't known was there: the "Follow TCP Stream" 
option. Really useful stuff...
