Somehow my Mac books fail to play all Quicktime movies whenI am accessing them through my browsers. Sometimes they play just fine. Other times I get the tranlucent Q. When I download the clip then the QT player plays them wihtout difficulty. This began when Apple went from QT 7. It was not a problem with Tiger or Leopard on my old systems. It began with Snow Leopard and continues with the Lion upgrade. The problem persists. I have Flip4Mac as an application along wiht Pages, Office Suite 2004 then recently upgraded to 2010. I also use the computer as a server with MAMP as the application.
This is problem that has persisted for two to three years. I've just worked around it using a nother computer. Seems now I sould actually fix it. If amyone knows of an adjustment I can make I would appreciate learning from you regarding this issue.
