Hello - I'm a Program Manager with the ISV Readiness, Ecosystem Engineering team at Microsoft. Microsoft is committed to providing the best possible end user experience for each new version of the Windows Operating System. Windows Error Reporting (WER) gathers crash data, hangs, and bluescreens which provides an accurate portrayal of how an application or driver is performing in the marketplace. This allows us and our partners to identify and address reliability issues.

Ref 383797 - Hang in splitter.ax!Unknown.  ProblemClass: APPLICATION_HANG_BlockedOn_EventHandle (cfffffff)

On June 26th, Microsoft announced the availability of the Windows 8.1 Release Preview which can be downloaded here: http://windows.microsoft.com/en-us/windows-8/download-preview

Microsoft has identified a reliability issue with splitter.ax that is occurring on Windows 8, Windows 7, Windows Vista and early telemetry data is reporting the hangs occurring on the Windows 8.1 Preview.   The hang was reported by users when the UI thread became unresponsive for > 5 seconds.  This is affecting mpc-hc.exe and wmplayer.exe the most.

Here is a Stack Trace:

        [000] ntdll!ZwWaitForSingleObject

[002] kernel32!WaitForSingleObjectExImplementation
[003] kernel32!WaitForSingleObject

[015] user32!DispatchMessageWorker
[016] user32!wcscpy_s
[017] mpc_hc
[018] ntdll!_RtlUserThreadStart

Is there a newer version of splitter.ax available that would fix the hangs being encountered?  Thank you for your assistance.
