Q: So why can't my QT version 10.0 (90.3) play h264 files?

My operating system is OS X Version 10.6.1.

 

The error message I receive is:

 

The document “opening doc5 4x3.mov” could not be opened. The movie is not in a format that QuickTime Player understands.

You may need to install additional software to open this type of file.

 

The Tell me more button takes me here:

What do I do?

Mac OS X (10.6.1)
