QuickTime Pro keeps crashing when I open "Show Movie Properties"

Question

I keep getting the "QuickTime Player has encountered a problem and needs to close. We are sorry for the inconvenience." crash when I try and do "Show Movie Properties" on .MOV files.
The error signature is:
EventType : BEX P1 : QuickTimePlayer.exe P2 : 7.65.17.80
P3 : 4afa5828 P4 : QuickTimePlayer.dll P5 : 7.65.17.80 P6 : 4afa5820
P7 : 0000130d P8 : c0000409 P9 : 00000000
Any suggestions?
I'm running the latest QuickTimePro (7.6.5) on WinXP SP3

Answer 1

in fact it's one of the few bits of Quick Time that seems stable on my PC!
Hmmmmm ... your symptoms aren't typical for what I'm about to check on. But I think we ought to check to see if any other application has sprayed old QuickTime componentry into unorthodox places on the PC. (That's one possible cause of a BEX.)
(1) Go Start > My Computer.
(2) From the Tools menu, select Folder Options ...
(3) Click the View tab.
(4) Make sure Show hidden files and folders is selected and Hide extensions for known filetypes is unchecked.
(5) Click OK.
Now head down into your C:\Windows\system32\ directory. What files and folders with QuickTime in the file/folder-name can you see in there?
(In a standard QuickTime installation, you should see precisely two files, QuickTime.qts and QuickTimeVR.qtx, and no QuickTime folders whatsoever.)
