           Version: unspecified
          Hardware: x86-64
                OS: Windows
            Status: NEW

mfplay:mfplay sometimes times out on Windows 7:

mfplay:mfplay:0a24 done (258) in 120s 0B

See https://test.winehq.org/data/patterns.html#mfplay:mfplay

The test normally runs in under 1 second which means the time out is caused by
a deadlock. However this is pretty rare and has only happened in 1.6% of the
WineTest runs and only on Windows 7:
