Have you gotten Sniffer Pro to successfully read the IP packets?

If so, what does it show for the Frame Relay headers?  I.e., is it
treating the address field as an address containing only one octet? 
Q.922 says "The address field shall consist of at least two octets",
meaning that the low-order bit of the first byte of the address field
must be zero, but that byte is 0x0f in all the packets, as noted by Tom

If not, then the problem is that they're not valid Frame Relay
packets according to Q.922....
