Saying you care about data economy and then installing a mega codec pack such as CCCP is contradictory. I only use MPC-HC as a player, but I have one by one installed the supporting components until everything plays (not much was needed, though I installed a couple of more to be able to encode). A CCCP (or any other codec pack user) has installed a whole bunch of stuff and then hopes something in all that mess will play the video.

But I do understand your other reasoning. Everybody's busy these days, after all.
