What program can you use to see if someone may have been hacking, ie smoke or wall hack? I use seismovision to watch demos but that doesnt tell me much.

Druid uses grincam, but I can only find it for UO, not cod2. I can send you a nice demo I took of a noob with cham skins. He was soooo bad, yet clearly hacking, lol.

grin cam works for cod2 but has limited abilites do to sv_cheats 1 locked.
There is a work around for this in the grincam forum

You change your normal shortcut to start COD2 with grincam with this
+set sv_cheats 1 +devmap mp_trainstation +exec vcr.cfg +wait +wait +disconnect

This fakes the game into allowing sv_cheats 1

The other change you want to make is inside the vcr.cfg file replace
bind kp_home "developer 0; toggle r_shownormals white '; wait 5; clear; developer 1; echo Toggle Shownormals Mode"
with

bind kp_home "r_xdebug 2"

r_xdebug 2 will change players into a wireframe starburst you can see through walls to check for wallhacks

So confusing... Until it becomes a "put file here and hit play" I won't be able to use anything like it...

lol, thanks druid, lets see how this goes
