Perian on a clean Mountain Lion

After I upgraded from Lion to ML when it came out, Perian just continued working without any problems, making QuickTime Player (X) play pretty much whatever I threw at it.

However, I recently performed a clean reinstall of ML on both my computers and now Perian doesn't work for me at all.

I came across some articles that Perian does indeed have issues under ML, especially with clean OS installs. I read that I should install QuickTime Player 7 to make Perian work again. Does that make sense? Willl this make Perian work with QT X as well or will this work only in QT7 now? I never ever had QT7 installed on any computer before, just the default X.
I play most files in VLC now, and I don't mind it too much, VLC is great and multiplatform, but I just prefer QT for its speed, simplicity, Mac-like-ness and hardware acceleration.

Thanks for enlightening me, I'm really confused...

Thanks, I knew that - but so far it works fine. Unless it doesn't, like in my case.

Really? Just like that? You didn't have to install old versions of QT, it just worked for all your files? Good for you. I'll try that again, maybe I did something wrong.
