This is the first time i've chimed in on this group, but i had the same problem with QT7 and FCPHD (I believe i have version 5). None of my FCPHD projects would open after installing QT7. Even after downgrading to QT6 again, i could get the projects to open, but any audio track with an EQ adjustment wouldn't play without an error. If you get to this point you can just simply delete any EQ adjustments and reinsert them again and the tracks should work. In my case, this wasn't an option as i had - literally - hundreds, if not thousands, of EQs applied to my hundreds of tracks. My solution was to wipe my main drive completely clean and reinstall from my original disk and allow software update to update everything EXCEPT QuickTime. I have only allowed updates to QuickTime up to, but not including, QT 7 and everything has been humming along beautifully. I'm running a dual 2G G5, OS 10.3.9.
