Decoders are used from multiple thread, so they need to use the MTA if 
anything.

AFAIK SAPI was always wrong, as was pointed way back when it was reviewed. But 
that is a different issue: it assumes that the MTA is referenced and kept 
around out of thin air. In practice it works because something else, e.g. the 
mmdevice plug-in, sticks around with the MTA.
