OpenGL export is messed up

Hi, I use code from the QCTV example to export video from my quartz composition, which works fine on my G5, but when i use it on an intel macbook, the video export is messed up, as if the image has been sliced up by a giant tiger paw, smearing all the color out in one direction.

The strange thing is that the original QCTV example works perfectly on the intel macbook, while my homecooked app doesn't. I can't find any difference between the applications on that part, does anybody here know what can be the cause of this?

These are my opengl attributes:

NSOpenGLPixelFormatAttribute attributes[] = {NSOpenGLPFAAccelerated, NSOpenGLPFANoRecovery, NSOpenGLPFADoubleBuffer, NSOpenGLPFADepthSize, 24, 0};

Thanks
