Another potential fix for choppy playback in QuickTime 7.5
Wednesday, July 2nd
Users who updated to QuickTime version 7.5 have been plagued by some annoying problems, including choppy playback, as noted here.
As previously reported, many users have resorted to downgrading their QuickTime installation to version 7.4.5 by using Pacifist. However, some users found choppy playback to be associated with improperly loaded plug-ins and add-ons from third party vendors as well as those included by Apple with prior versions of Quicktime.
Third-party add-ons include DivX, Flip4Mac, or FLV components, while the included plug-ins are AppleIntermediateCodec.component, and AppleMPEG2Codec.component. The files for these are located in the root library, therefore a faulty component will load improperly for all users, resulting in choppy playback even when a user creates a new account.
Fix
- Remove and re-add all quicktime components and plug-ins.
- Navigate to /Library/QuickTime/
- Move all plug-in ".component" files from the folder (to the Desktop, for instance)
- Launch QuickTime and quit it again
- Place the ".component" files back in the QuickTime library folder
- Launch QuickTime again, and the choppiness should be better.

Am I missing something?
But here's a twist. Take your choppy movie and export it to a WMV (Flip4Mac). The resulting WMV plays fine in both the Windows Media Players and Quicktime. But in QTime Pro take the same WMV file and re-export it as a Quicktime file and it's back to it's choppy self again.
So it seems that the problem with Quicktime is reading Quicktime files. Windows files are fine. Of course, that doesn't help those if us who depend on QTime to make a living. My DAW is not going to read a WMV file. It want to see a QT file. And so do I, darn it!
Apple needs to place this at the top of the list.

(3 Comments)Doesn't anyone clean up or monitor MacFixIt anymore? Or is it just part of C|Net (soon to be CBS)'s downgrading since buying Ted out?
