This muxer is an interesting tool indeed, however it does have a major limitation --- quite often (not to say "always"), it just preserves the ASF index if the source file already contains an index, but it does not create an index for a b0rked WMV, and this fact may result in corrupted/unplayable remuxes. Depending on the case, you will have to use the old vidtoasf.exe, OR a decent build of ffmpeg, together with AsfBin.
