On an Indigo2 Extreme (IRIX 4.0 and Performer 1.0) I need to be able to direct
the Performer image output to an NTSC video type display (specifically RS-170
video format). We will probably be using a Galaleo video board. How does one
cause the graphic output to be routed to the video board (assuming that it is
possible)? I do know that there is a broadcast video option (BVO) available
which will scan convert the console image to NTSC, but we would rather use the
video board if possible.

Also, does anyone know anything about the internals of the pfDraw? Does the
draw go directly to the video memory, such that the image is updated
immediately, or is the video buffered such that the image will not appear
until the next video frame? We have a latency requirement of 150 milisec that
we must meet and are trying to account for each step of the process.
