This decoder functionality is built into Media Player Classic, although prior to the recent release, or CVS builds if you were keeping up, the Matroska filter was a little behind current development. In which case, you would have been wise to disable the internal splitter and install the official DirectShow filter.
So, once again. Media Player Classic, ffdshow*, QuickTime (Alternative, if you prefer), Real (Alternative, again, if you prefer), and maybe the Matroska splitter. If it still doesn't play, it probably wasn't worth downloading in the first place.
* Be sure to reconfigure ffdshow at least once after installing. Rundll32 ffdshow.ax,configure, if there's still no supplied shortcut or utility. There are a lot of mostly bug-free decoders which are disabled by default, some of which either lack a DirectShow decoder or would require their own dedicated filter.
Oops, almost forgot VSFilter. While MPC does have built-in subtitle support, it is minimal compared to the full VobSub package, or even VSFilter. Hmm, strike that, I almost forgot that ffdshow has built-in support for subtitles, and should be sufficient for most cases.
Crap, details just keep coming up. I guess MPC only supports the OGG container, but not Vorbis audio. Bleh, throw in CoreVorbis as well.
