If you do end up building a custom solution, I have a feature request :-)
It would nice if the device was also a frame grabber that could, under
command, snap one or more frames of the legacy video and export it over
USB perhaps.
This would allow us to document operation of legacy software with high
quality frame grabs since persumably you'd have access to the image
in a relatively good quality domain before you turned it into DVI/HDMI
or whatever.
