Keep in mind that ethereal only shows what data is in the packet. It's not a
full human readable dissector. You have to know your protocol to fully use
ethereal.

Not impossible, but not the best thing to do. Once you have the packets decoded
using the DIS dissector it's all you need. To understand what the values stand
for you need the IEEE specs for DIS, and mainly the EBV-DOC from
http://www.sisostds.org/. Once you have those it's easy to look up the values.
