old tf2 maps got those videos:
2fort
ctf_ and cp_well
pl_goldrush
cp_badlands
etc...

do anyone know how to do that?
i know i probaly will need .bik format video with 480-360resolution like the original has.

 

This tutorial is what you're looking for. I think it breaks if you pack it into the BSP though, so you'll need to provide it as part of a ZIP file.
