Im certainly not telling anyone to infronge copywright on their products, although personally I find it very grating that Apple dont offer the components for independant install as thats exactly what things like Flip4Mac are offering, and its all that FCP does to your version of QT when you install FCP, without any form of notification I might add.
My reasons for needing to try this is because of the backwards compatibility with FCP, if Apple didnt force this issue then there would be no need for work arounds.
Noah, on your warning of techical issues, quite what trouble you expect to run into by installing components in an extensions folder that are designed and made by Apple developers for this exact reason I dont know. Read developer info and you will find that this is common practice for building new video products that are to be used with QT architecture and it is much more risky to use 3rd party products than using Apple developed components in this way anyway, and that accounts for many plugins for mac in itself, what I shared with other readers of this site is that I moved Apples own components into a folder made for this process. If your suggestions are just go out and buy software and wait until it works then whats the point in half of the posts on this site?
