The best video is the amateur video that was sold to Australia's Seven News, which showed the wave coming into Phuket, Thailand. Seven has a sourcing agreement with NBC, so I'd suggest checking MSNBC, an NBC affiliate or MSNBC.com for the video itself.
I have been disappointed with the (limited) coverage by the United States media outlets also. They are not meeting the demands of the worldwide audience in providing decent information and coverage.
If CBS can fly Jeff Probst around in a helicopter to film "Survivor" segments, surely to God they can do the same for some reporters.
