Hey everyone -


Any thoughts as to why I'm seeing a white screen (no video) and audio when streaming a .mov file from a website?


The computer in question has Quicktime 7.7.2, plugin is enabled and is running Windows XP SP3.


I've tried removing and reinstalling Quicktime, upgrading to 7.7.3 and downgrading to 7.7.1 - no change.


The issue persists using Firefox, IE 8 and Chrome.


I can play the video fine on my MacBook Pro (running Lion) and on another Windows workstation - different PC model but everything else is the same.


Any troubleshooting suggestions would be fabulous.



MacBook, Mac OS X (10.7.2), 2GHz, 4GB RAM, 500GB hard drive

    Hi Lyssa,


    on your Windows PC open QuickTime Player. Click edit > settings > quicktime settings. In the appearing window click the last tab and select safe mode (gdi only) in the video section.

    Hey Matthias -


    Thanks for the suggestion! I changed that setting, but I'm still seeing the white screen with no audio.


    If you have any other suggestions, I woul greatly appreciate it.

    hmmm… maybe another video capable application has grabbed the .mov extension on this particular pc or the QT browser extension is disabled in the browser itself. You can check this out at the standard applications pref pane (hope this is the right name, I only have a german xp here) and in the browsers plugin settings.

    Went through and disabled any plugins that could be grabbing it & no joy...I can get it working on another PC that is absolutely identical (same graphics card, software installs & network configuration).  Most puzzling!


    I think we'll just download the videos from this point forward and try the plugin periodically; eventually it'll start working again.


    Thanks for your help!

    You're welcome.

    There is one last suggestion. Is it possible that QuickTime is accidentally blocked by the windows xp firewall for incoming connections on this pc or the streaming protocol isn't set to automatic in the QT pref pane?
