MPEG Streamclip and Snow Leopard

I thought this might be useful for those of you who use MPEG Streamclip and have just upgraded to SL.

If you have you'll see it's missing the MPEG2 component and won't work properly and it's not easy to get back unless you have time machine backups etc.

Here's a cast iron way of restoring it and without installing rosetta which you will encounter if you try installing it from a regular PKG file:


First go to your FCP DVD and right click the installer and 'show the original file' from the shortcut icon:

Find the QuickTimeMPEG2.pkg or QuickTimeProMPEG2.pkg

Right click on the QuickTimeMPEG2.pkg file and choose "Show Package Contents".

Open those folders and drag the one named Archive.pax.gz file to your Desktop.

Double click to expand it and drag the QuickTimeMPEG2.component to your
HD/System/Library/QuickTime folder and restart your machine.

Delete the files and folders made on the Desktop by the Archive.pax.gz file.

Job done, all should work fine now!

Really? So when you upgraded to SL you lost all of your 3rd party apps, and had to reinstall everything? It's less likely that it was deleted, but rather it wasn't recognized. Upgrade install is the least secure, as the upgrade doesn't take into account the different file permissions and system directory structure of the previous OS, and can result, as it did for my most recent client, in hard drive space being locked out. He had 38 gigs on a 60gig drive, but the computer said he only had 7 MB of free space. Avoid upgrade installs at all cost.

I didn't lose them but a lot of functionality was lost - anything that used that MPEG2 plugin no longer worked until it was manually restored.

I've been using Snow Leopard in an upgrade situation on 3 machines now for a few weeks and everything is pretty stable, just problems with unsupported apps which are slowly being resolved as the weeks go by.
