Windows CE 6.0 Video Renderer - RGB 565 display problem ???

Question

Hi All,

I have written a Source filter which provides RGB 565 data to Video Renderer in windows CE 6.0.

The problem is i am trying to play a video file using this design and if for example I change the size of my video window less than the original video size then there is some disturbace introduced in the output.

It shows the output as for every scan line first few pixels are copied same to same in the end of scan line for around 8-10 times.

I checked the stride etc is not changing. What could be the cause ... Can anyone suggest ???
