Scorpion, i've found the cable on ebay when i did a search for RGBHV MALE
(i can't post a link being a new user to this board).
It's listed as a 'ATLONA VGA ( FEMALE ) TO RGBHV ( MALE )BREAKOUT VIDEO ADAPTER'
and
'Atlona`s VGA breakout adaptor is designed to connect RGBHV video sources to VGA displays such as ( Video Projectors, HDTV Televisions, Computer Monitors) or could also be used to connect VGA sources ( such as Computers, Line Doublers, cable boxes, satellite receives, game consol's ) to a RGBHV display. Adapter is bi-directional, therefore signal can either be sent from RGBHV to VGA or VGA to RGBHV . Adapter comes with BNC female to RCA male adapters which could be used if display or source requires RCA type of connections.'
Do you think this would work? It looks like cables only, ie no boxes with electronics inside...
