    Resolution Note (fix version 2020.1):

    Async media file read on Win7 Media Foundation has different behaviour than in >=Win8, leading to reads all happening in one chain of calls. Works for smaller files but not for large files. Reworked to make the logic compatible with all versions of Media Foundation.
