I used to be able to play lagarith with MPC-HC, but now I can't. It's not that big a deal though. Lagarith is used mainly as an intermediate codec to keep everything lossless during the editing process. As long as I can play it back with virtualdub, it doesn't really matter to me if I can play it in media players or not since lagarith isn't a release format.
