#3ds & Sanyo GVRS-950
I have the exact same setup as you. The sign you need to put over your
VTR should read "MAKE SURE THE VIDEO INSERT MODE IS ACTIVATED!" What
I mean is, you have to set the GVR into a video insert mode, or you
get this result. Happened once to me, too… Hitting the initialize
button on the VTR setup menu ought to set it up correctly. You can
also do it from the front panel.
