Cubase Video Import

Hello People.

I search the internet to fix this problem.
I installed quicktime player for the right codex.

I put the video rate with project setup settings to the right frame rate.

The problem is that cubase still saying ( when i import a video Divx ) Missing Thumbnail Cache.
When i right click go to media and create thumbnail or i go to the pool and i do the same, the problem excist.

Do you know what i do wrong ?

Kind regards

Can you try different codec? MPEG for example?
