A solution. The other day using Safari as my browser on a iMac with the latest version of Lion installed, I visited a web site that had an embedded QuickTime video, demonstrating a piece of software that I was interested in. The problem started when the video did not show up, just an empty space with the words 'Plug in failure. I started to search the net, and found that a lot of other people using Lion and Safari were having the same problem.
Well for me and I hope for some of you as well, I have found a solution to the problem. However this solution will only work if you have 3ivx on your machine.
First go to Settings and have a look at the bottom line and see if 3ivx is installed. If it is go to your Applications folder and find the 3ivx folder, it will be near the top of the list. Open the folder and inside you will find an uninstall package for 3ivx. Use the uninstall program to get rid of 3ivx.
Once you have done that, I would suggest that you run verify and repair permissions, but you may find all will be well without doing that.
Open Safari and return to the site you were having problems with, you should now find that the QuickTime video will be there and you will be able to play it.
For some reason upgrading to Lion and the latest version of Safari has caused a conflict with 3ivx, causing the QuickTime plugin to malfunction. I hope that for some of you with this problem the above helps.
