Seems high frame-rated clips such as this one require a hardware set with at least 2000 MHz of CPU speed and at least 512 MB
of RAM. Players seem to drop frames just when the scene changes the most (hence the irritating drops) and the system is temporarily unable to cope with the decoding. The 3D or gaming performance of the system is irrelevant here.
The current release of Microsoft Media Player 10 plays this clip "off the shelf" without any additional codecs being needed. Mr Gates' enterprise provides
the MP10 free at the company website, no obligations or spyware attached. (There are some freebie players that come with a little bit of unwanted extras)
I tried to listen carefully to the soundtrack, but you'd have to be multilingual with very fast spoken Finnish (pilots discussing the user interface of the avionics computer, for instance), Aviation Finglish (used by the crew and the Finnish Controllers), and of course US Aviation English, and have a very keen ear. It is no wonder the actual cockpit recordings use hot miking.
