How To Figure Out Which Codec Is Used?

[Biggest_Baddest_Wolf]

Hiyas....
I recall a post that lead me to a tool that gave information on video-files, in particular which codecs a movie or clip used, but I lost that tool some time back.
And now I did a search, but didn't come up with the post I was looking for, so here goes nothing... heh...
Does anyone know the name of that program?
I got all the codecs I need so I haven't got any problems, but was talking to a friend about it because he would have a use for it, and then I found out I didn't even remember the name of the thing lol...

GSpot, comes with codec pack

[Rip The Jacker]

AVICodec (http://avicodec.duby.info/).

Ah yeah, Avicodec was the one I meant.....
Kudos.

And wouldn't you know it, just when I think I had every codec I needed, I get a file that needs another one lol.... ah well, I already solved that, was some weird codec that I found on google.
Anyways, I'll suggest both tools to my bud, sounds like he might wanna give them both a spin.
