VSE 8.8 P4 + HIP 8.0 P6 is not a good combination.
You should update either (or both) to a current patch level. There are stability risks we learned of from the field with P6 code.
FYI, almost all crash dumps with our products installed will point to mfehidk.sys
- because the debugger has logic that looks for the first non-Microsoft driver it can blame, and
- because mfehidk is our pivotal driver receiving I/O from the filter manager; it martials events off to our other drivers as needed, thus it's almost always present when a failure occurs.
