Beware Quicktime 7.5.5

I had a bad scare yesterday. Having stupidly said "yes" to an automatic upgrade that Apple told me to install, I suddenly couldn't get final cut pro to start up. I tried something recommended by one Mac hints site, starting in safe mode and fixing permissions and re-installing by hand the Quicktime update that the upgrade included (the other thing that it included was the new version of iTunes, which includes the new, slightly creepy and very annoying "Genius" feature. bleah.).

That got FCP to start, but i was unable to capture or output to or from firewire devices. In fact I couldnt get any application to not crash when i told it to access my firewire DV deck. I was freaking out. What to do? Would I have to reinstall OS X from scratch? wipe my hard drive in order to go back to the old version of Quicktime?

Luckily after one more desperate Google search I found a page that described how to downgrade to an earlier version of any Apple package using a little program called Pacifist (funny coincidence that a program called Pacifist has enabled me to continue work on a film about resisting war!).

I got the shareware and followed the directions to install the earlier package, Quicktime 7.5, and restarted and things now seem hunky dory again. Whew. I think I owe a registration fee to Pacifist's creator.

Anyway, if you are a user of FCP (at least version 5.1.2) and you haven't upgraded to the new QT, you might want to think twice before doing it. Oh, and I recommend skipping the new iTunes as well. By the way, during my research into this problem I read that the "security fixes" that Apple lists as the reason for the upgrade actually have to do with Digital Rights Management (locking up content) rather than any sort of protection from your machine getting hacked or that sort of thing. So the new version is pretty unneeded anyway.
