If it's not RTP, is it some other protocol that carries video streams
*and* that's dissected by Ethereal?

If so, perhaps that protocol's dissector puts sequence numbers into the
Info column (if not, perhaps it should), or even supplies some form of
higher-level analysis, e.g. with a tap similar to the RTP analysis tap.

If not, then Ben can't get what he wants, as you can't detect
out-of-order or missing packets at the UDP level, you have to go to a
higher level, and if Ethereal doesn't dissect the higher level protocol,
it can't possibly detect out-of-order or missing packets.
