You might guess that I've finally, with the help of you fine folks solved my dilemma.
Here is what I did so someone else with the same problem can try this.
1. Search C: and type in "MatroskaSplitter"
Result: [u]MatroskaSplitter[u] C:\Windows\System32
That will tell you that you have the file on your computer.
2. Control panel>Add/Remove>Media Player Codec Pack 3.3.1
3. Click on Change/Remove
4. Choose Custom uninstall and deselect all and find Haali and delete it from the program. I didn't want to delete the entire file for fear that it could affect something else.
5. Restart Windozs
PD7 loads in lightning speed and the movie is flawless.
Enjoy!
Thank You,
Cheers
