After getting the 64bit versions of ffdshow and haali media splitter I was able to get mkv files to play in vmc. When I try to play flac however, I get one of two error messages. The first one is an error code CD00FEDA (or something like that - I'm going off memory) or cannot play file. Sometimes I will get the first error, then when I try to play it again it says the file is missing. It may be corrupt, or missing. The files are not corrupt or missing. I ripped 4 cds with EAC and the files play on my other PC. Windows understands what flac is because it is linked to VMC. Also I've enabled flac in ffdshow. Is there a certain file structure that is needed? Any ideas what the problem may be?
