OSD is getting compressed in digital LCD display in DM6446.

Dear all,

In my DM6446 evaluation kit,  I am feeding PAL SIGNAL  and display out is digital LCD. The output video is integrated with OSD (RGB overlay ). Now the problem is , I am getting proper display but OSD is compressed and display it in half of the area (720x300 approximatly).  But my video out is 720x576. I can get the full area of OSD in compressed format and  display it in half of the area...

Should I increase the buffer size of VPBE and VPFE ? or what changes i have to do to get the full OSD (720X576) with integrated video ..?

Kindly let me know if you need more information about our product..

Thanks a lot..
