quicktime with question mark?

I found this helpful solution on another mac forum. Hope it helps.
1) Open the folder Macintosh HD/Users/your_user/Library/Preferences
2) In this folder, search the file com.apple.quicktime.plugin.preferences.plist
3) Open it with Textedit
4) Search for this string (without the quotes) "<key>application/x-shockwave-flash</key>"
5) On this section, change the "<true/>" string to "<false/>" (without the quotes)
6) Save and quit Textedit
7) Relaunch Safari and ENJOY!!!!!

Just wanted to say a big THANK YOU to Mena for this reply to another member here.
I have been round and round with this problem for weeks and your answer solved it.
Bless you, Mena.

Wow, that really solved the problem. I'd got the same issue. Thank you very very much!

This should really be marked as a 10.5 (Leopard) fix.
For some reason the older .plist file (moved from a previous OS) isn't being updated to show the proper MIME Settings for Leopard.
QuickTime 7.2 (and under) has a user adjustable setting for Flash Video (MIME Settings/Miscellaneous) but this has been deleted in version 7.2.1 (installed by Leopard).
7.3 also has no user MIME Settings adjustment for Flash Video but some users have carried over the older .plist file.
Deleting the com.apple.quicktime.plugin.preferences.plist and relaunching any open browser and QuickTime Player should create a new .plist file with the correct settings.

Oh no- spoke too soon. It's baaaccck!
I am running Tiger by the way.

You're a gem Menna, thanks for the posting

I recently installed the Xvid component for QT and started noticing the problem of quicktime with the question mark as well as crash issues with Toast Titanium 8 and Popcorn 3. I uninstalled the Xvid component and the problems seem to be gone.
Similar issues, anyone ?

It worked for me, thankyou for taking the time to help us out.

This absolutely fixed my problem too!! Just wish it could have been a simpler solution (Apple!) , but really glad it's fixed. Thanks for great posts to the forum.

Hi Mena, I've followed your instructions regarding Q? issue (a Flash problem I think!), once I got to the
part of applications Xshockswaveflash... the word in between the was dict/ and not true and nothing happened when I typed in false, saved, applied and restarted. Do you have anything else to suggest? Laurie Joseph

My thanks too - I had not been able to view Quicktime files for several weeks and it was starting to be a big inconvenience.

The fix supplied by Mena N worked for me! My gratitude and blessings go to Mena N
