Yes.

The DC10+ can use "virtual memory blocks" for MJPEG capture (so memory
allocated in small pieces in random places in the physical RAM). That's
how most capture stuff works. However, for raw capture, it needs
physically contiguous memory. This means that it has to be one block *in
the physical RAM*. The idea here is that normal users don't use this
anyway, you only use this for overlay (display) on the hardware memory
of the video card, and that actually *is* physically contiguous. So it
makes sense, except that you want to use it differently then how the
developers of the card intended it to be used.

HTH,

Ronald
