That was an ABC News production. They have a library of archived footage here:http://www.abcnewsvsource.com/
I don't think the segment you want is online, but that page gives some contact info you may find useful.
BTW I think that title was ripped off from the 1997 Broughton Coburn book about 1996, centered on the Breashears expedition. Published by National Geographic, ISBN 0792270142; you can find used hardcover copies selling for 99 cents online.
I don't think ABC news had their own film crew anywhere near Everest, so I assume the Turning Point footage was largely borrowed from the Breashears expedition's IMAX footage.
