I don't believe they ever implemented that as a Media Foundation codec,
which is what WMP11-Vista uses for ASF playback. Windows 7 adds an ACM
wrapper for Media Foundation, so this clip should work there again (once you
install the Sharp ACM codec) through that extra bit of backwards
compatibility. =\
