K-Lite Codec Pack Standard 8.4.0

Pros:  None

Cons:  None

Other Thoughts:  If you don't need all hell of codes, then stick to the standard package. I did so for a long time. K-Lite was always great.

But recently I switched to "XP Codec Pack" (www.xpcodecpack.com) which is also a great codec package. And I think it's slightly better. It's your choice.
