I went over to the VCP(vista codec pack, also win7 codec pack) site and talked to the creator of VCP, after a little test hes putting monogram's filters into his next build since the current filters he has installed as part of the pack DO NOT SUPPORT SV8.
If anybody is intrested check out http://shark007.net/forum/Thread-Musepack-mpc-codec (http://shark007.net/forum/Thread-Musepack-mpc-codec) and http://shark007.net (http://shark007.net) (for downloads)
I have been using VCP for over a year now and the rare times its had issues shark007's been very quick to address them, and if you have a suggestion/request, as the first link shows, hes very willing to listen
