My Quicktime is hosed! I cannot view any videos (.mov, .mp4, or .m4v) in any application that uses QuickTime: I get audio only, with a black picture (no video other than blackness) in QuickTime Player, Safari, iTunes, and even in the Finder's Quicklook and Cover Flow views....only black, with audio!

I am at a loss! Any ideas? I am using QT 7.3 on Leopard 10.5.1. Thank you!

    I have a similar issue. Just have purchased QuickTime Pro and registered with the key accordingly. However, the format (MPEG-4 AVC/H.264) cannot be opened. I only have a green background screen and can listen to the to the audio recorded.

    Also tried in i-Tunes, but still audio only and a green background.

    Furthermore, when I want to open QuickTime Pro, only QuickTime is visible and neither 'Pro' appears in the logo nor in the applications. However, once I go back to registration, the key I purchased is still there.

    I am lost as well. Any ideas?

    I looked in my QuickTime folder inside the top level Library and thought it might be prudent to remove some third party components and see what happened. Immediately after removing all of the Flip4Mac components, Perian, and DivX 6 Decoder, I rebooted and my .mp4 and.m4v Quicktime movies were back in action. QuickLook, Cover Flow, iTunes, QuickTime Player, etc., all play them just fine now. What's odd is that I did not install any of those recently, so I am not so sure I have solved my issues, but at least QT works again and I will not miss those decoders for the time being, until I have the time to reinstall them one by one and see what happens.

    When you get around to reinstalling, try this:

    These are the downloads and the settings you need in order to view/hear pretty much everything that the net can throw at you: The setup described below has proved repeatedly successful on both PPC and Intel macs, but nothing in life carries a guarantee!

    It is known to work in the great majority of cases with Safari 3.0.4, QT 7.3 and OS 10.4.11.

    Assuming you already run Tiger versions OS 10.4.9 or above (this has not yet been verified with Leopard) and have Quicktime 7.2 or above, and are using Safari 2 or 3, download and install (or re-install even if you already had them) the latest versions, suitable for your flavor of Mac, of:

    RealPlayer 10 for Mac from http://forms.real.com/real/player/blackjack.html?platform2=Mac%20OS%20X&product= RealPlayer%2010&proc=g3&lang=&show_list=0&src=macjack

    Flip4Mac WMV Player from http://www.microsoft.com/windows/windowsmedia/player/wmcomponents.mspx (Windows Media Player for the Mac is no longer supported, even by Microsoft)

    Perian from http://perian.org/

    Adobe FlashPlayer from http://www.adobe.com/shockwave/download/download.cgi?P1ProdVersion=ShockwaveFlash

    (You can check here: http://www.adobe.com/products/flash/about/ to see which version you should install for your Mac and OS. This: http://www.macworld.co.uk/news/index.cfm?email&NewsID=19845 may also interest you.)

    In Quicktime Preferences, under advanced, UNcheck Enable Flash, and under Mime settings/Miscellananeous only check Quicktime HTML (QHTM).

    See also the very informative post from QuickTimeKirk dated Dec 3, 2007 in this thread: http://discussions.apple.com/thread.jspa?threadID=1268489&tstart=0

    In Macintosh HD/Library/Quicktime/ delete any files relating to DivX (Perian already has them).

    Now go to Safari Preferences/Security, and tick the boxes under Web Content (all 4 of them).

    Lastly open Audio Midi Setup (which you will find in the Utilities Folder of your Applications Folder) and click on Audio Devices. Make sure that both Audio Input and Audio Output, under Format, are set to 44100 Hz.

    Important: Now repair permissions and restart.

    The world should now be your oyster!

    You should also consider having the free VLC Player from http://www.videolan.org/ in your armory, as this plays almost anything that DVD Player might not.
