Channel 4 documentary - Papua New Guinnea mountain climbers

[Barnacle]

Can anyone tell me the name of the documentary, and where I can find a copy, of two blokes who set out to climb a really high mountain in Papua New Guinnea, amongst cannnibals, getting foot-rot, nearly falling.. etc. They made it to the top. It was a brilliant documentary, but I don't know who made it, or what it was called, or when it was made. Help.
