Flip4Mac and video engine

From the release notes:

14042: Video cannot be used, the application is crashing (Mac OS X only)
In case you are using “Flip4Mac”, please uninstall it as it is not compatible with our video engine.

I guess this would explain the “video engine not responding” bug that I have. However, I have Flip4Mac installed on two computers, both with same OS and version of Cubase, but only one has that bug.

Is there an alternative to Flip4Mac? I need it in order to be able to open and edit AVI files in Quicktime7Pro.
