Hi Chris, Jamie a.o.
The horizontal lines don't really look like interlacing, it's really a
field-swapping thing. The more you move the camera the more you see
those horizontal lines going down your screen. You have 1 or 2 lines on
the screen that seems to break the image in half and it seems the video
cannot keep up with the speed in which it's moving.

I looks like the object ieeel394 works the same like pix_video. The
quality 0 or 1 can be set followed by the reset message, but that
doesn't make it any better.

This is true. But, isn't there anyone out there that has the same
problem? [Or is nobody using the pdp firewire object] If it is a case of
updating / changing some libraries, then I can at least do something
