Quicktime Player 10.0/iMove 8.0.6 not able to read MPEG-2 1080HD Linear PCM Video

Bump.

Would any of these plugins listed on Apple's QuickTime Software Resources Page enable iMovie '09 & QuickTime Player to work with my Mpeg-2 files?

Welcome to the QuickTime third-party component page. With QuickTime’s open architecture, third-party developers can create components, or plug-ins to QuickTime. These third-party components expand the functionality of QuickTime, allowing QuickTime to play additional media types. If you encounter media that requires the installation of a third-party QuickTime component, please follow the link below to the third-party developer’s web site to see if it is available for download.

Note: If you are using a Macintosh with an Intel processor be sure to visit the component developer's web site to download a Universal Binary Component that is compatible with your Intel-based Macintosh. PowerPC-based components will not work in QuickTime on Macintosh with Intel processors.

I went to the genius bar and they told me I needed this plugin, but after dropping $20 on it, it doesn't work:

QuickTime MPEG-2 Playback Component for Mac OS X

This add-on to QuickTime or QuickTime Pro provides the ability to import and play back MPEG-2 content, including both multiplexed (also known as muxed, where the audio and video tracks are interleaved together into one track) and non-multiplexed (also known as elementary) streams.

Anyone have any other suggestions?
