mpeg-1 codec in drivers or hardware support?

[mitsukai]

hello all. i have wmp and wmp 6.4 removed

than i remove also some drivers and hardware support(most of them)

i have addon k-lite mega codec pack which has wmp classic player..

when i run any sound file, mp3 or avi, i get a mpeg-1 codec missing.

Now i keep all drivers and hardware support.

when i run any sound file, mp3 or avi, it works...

so does anyone know what driver or hardware support is responsible for this codec
