Happens around 24:30
Also lots of nylon and barefoot scenes inthe movie
The mision Impossible scene is from the 2nd instalment a few years after the first few seasons. Different cast. Will track it down. Not the best scene as quite short
Edit: It is season 1 episode 8 "The Pawn". Starts about 8 mins in. Can't download it but have the Gorilla vid link I can DM...
If you google VP70 and vlc media player it will take you too the right codec sites.
I used On2 tecnolgies codec and it works on Win media player but not on Vlc or MPC.
By the original post date it's prob season 3. Not season four as that aired a month after the post, according to tv.com. Narrows down the search a bit.
