Re: bitblt problem
BitBlt Copies Pixel data from Shared Video Memory,(Normally sits between 640k & 1024k) however there is a second level of video memory, that bitBlt does not reach.. this is memory that only the Video processor can work with.
When using hardware accelerated functions, bitBlt will not be able to capture the results.
Also Hardware decoded video streams can not be captured by BitBlt..
