A lesson from WMP9/10

[mystvearn]

Previously I was saying that wmp10 was slow, lagging, but the task manager shows only 10% of my resouce is taken. I thought that WMP was corrupted, so I uninstalled it, reinstall it, same results. Slow playing. Using different software's were disapointing. Maybe too long on wmp.
Just this morning, i went through the Tools>options>performance>advance>Video acceleration.

Here there are two options under "use video mixing renderer"
Use overlays
Use High quality mode.(my problem came because this was checked).

So changing it back to use overlays, solved the problem and I can view the movie files now. So this is my result after meddling with wmp10.
