GPUDIRECT for video: problem with GL_TEXTURE_RECTANGLE_ARB

hi,

i've modified the LoopThrughWithOpenGLCompositing project, since i only have 1 card. and it works as expected.

however, i notice that if i simply change the GL_TEXTURE_2D to GL_TEXTURE_RECTANGLE_ARB, the

following dvp call will fail with status returning DVP_STATUS_ERROR.

status = dvpMemcpyLined( mDvpPlaybackTextureHandle, mExtSync->mDvpSync, mExtSync->mReleaseValue, DVP_TIMEOUT_IGNORED, mDvpSysMemHandle, mGpuSync->mDvpSync, mGpuSync->mReleaseValue, 0, mHeight);

my question is have you guys tested the GL_TEXTURE_RECTANGE_ARB option for gpudirect, and is that not supported with the dvp lib?

thank you very much!
