I have find error if you cleaning MRU with Jv16 and QuickTime.
Jv16 completely clean QTPlayerSession.xml
but it's not good, all preference is also include inside.
If you clean QuickTime MRU, you clean also all parameter..!!
for clean MRU, go->
on 64bits system:
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Apple Computer, Inc.\QuickTime\Recent Movies
or on 32bits system:
HKEY_LOCAL_MACHINE\Software\Apple Computer, Inc.\QuickTime\Recent Movies
