Codec?? Cant see video

Hey, I have some files that won't show up on my screen but I can hear sounds. I was wondering what I needed to download...

Also, I remember there was this package I could get that included every codec, realplayer, quicktime, etc...what package is that and where do I get it?

Thanks for your help

You can use GSpot to check the codec. The codedc packs are Nemo and K-Lite.

thanks man...what is Gspot though?

It's a myth.
