If you're having troubles with CCCP, you might want to try the K-Lite codec pack, or perhaps another alternative. I don't know about recent versions of CCCP, but the K-Lite codec pack install also allows you to set up MPC-HC with LAV filters.
I have a personal horror tale involving a (significantly older) version of the CCCP pack, so I'm admittedly quite biased against it, but current versions should be reasonably stable. What problem(s) have you experienced?
