What codec do I get?

[Opencloud]

My computer recently fixed a corrupted registry and has set all it's settings to default. Now no video files can play (avi, wmv..) but I have audio. I don't know how this affected BSPlayer, maybe it deleted some video codecs aswell?

Anywho I uninstalled and reinstalled the Divx codec, nothing. Tried the Xvid codec, nothing. I also tried the FFDShow Mpeg-4 Decoder (It didn't work in "Windows NT") and 3ivx D4 4.5.1 codec. Rawr, I dunno where to go from here. Say every video codec was erased, what is the magical codec that would make all the .avi files functional?

By the way I have Win98 and BSPlayer Pro 2.0 and this is what GSpot says. Heellppp mmeeee
