I am able to Preview KL using VLC, MPC, BSplayer, and sometimes AVI,
but usually in attempting to use AVI I get this.
Clicking on Yes takes me to...here
Right now I'm using KL 2.7 Beta4 but have had the same problem in the past
using v2.4.3 and 2.6.
Oh, and btw....I have the K-Lite Mega Codec pack installed.
It's not the end of the world as we know it if I get that message and
cannot use AVI for Preview but, I like to tidy up loose ends like this.
