Well, how can I spec another player in a demo? The position and aiming of that player seems to be recorded so how can I view that?

From http://urt.taggedzi.com/guideappendixb.php:

cg_thirdperson        0/1   0   Toggles 3rd Person view ONLY when in demo playback
cg_thirdPersonRange 0-500  40   The camera distance from the character when in third person mode
cg_thirdPersonAngle 0-360   0   The camera angle relative to the character when in third person mode

Oh, and there is already a config that makes use of the variables
listed above:
