To my knowledge, libraw doesn't support DMA transfer. Actually there is
nothing like that implemented in raw1394.ko. If you "acidentally" use the
libraw implementation of libdc1394, there is a big chance to have unnotified
dropped packets since the internal isochronous buffer is restricted to 4 MB.
