He spoke of the commercial products offering "more accurate decodes"; I'm
curious what inaccuracies he found in Ethereal's decodes.

He didn't mention Microsoft Network Monitor (perhaps because the
limited-capabilities free version comes, I think, only with the server
versions of Windows, and the full version is available only with SMS); it
also has a display filtering system similar to that of Ethereal.

He does say of EtherPeek that it has "the ability to quickly filter out
traffic you don't want to see in the display", but I don't know whether
that's just offset filtering or not (an EtherPeek for Mac manuals seems to
indicate that you might be able to filter on particular protocols, but not
on fields in a protocol).
