Thanks for ur response.
Can u tell me where to find study material about writing a driver to catch
low-level video calls. ( BTW can I use windows Hooks fro that purpose..
There may be some kind of messages passing around ).
As for Win9x , I assume DDI ( Direct Draw ) helps in creating surfaces
directly on videoMemory , I didnot get any idea about how to actually
capture Video Data from Video Card before it goes to Device driver

This depends on the platform. On NT, you need to write a driver to catch
low-level video calls before they reach the real video driver. Under Win9x,
you need to use the DDI interfaces.
