Quicktime playback issues in windows 8

For some reason quicktime files are choppy and jittery during playback in Windows 8.

I have the latest Quicktime installed with no other codecs.

I tried playback in the quicktime player as well as in adobe products (premiere, after effects, etc.).

 

 

Here’s a preview of what the playback looks like:

The same rotating star video plays fine on my windows XP machine.

 

 

I know this is not an Adobe problem but I was wondering if anybody had any ideas?
