I'm looking to use non-RGB video sources in my cab such as old consoles and the like. I already have a nice original 28" Hantarex arcade monitor in there which is great, but I want to connect s-video and composite equipment into it. There are a number of 'VGA boxes' on the market for hooking consoles etc. to VGA monitors, but all the ones I've seen scan-double to 31khz. I'm wondering if anyone has seen one which will allow you to disable the scan doubling, or a hack to an existing one, so you just end up with a composite/s-video to RGBS decoder? This is really bugging me because it's a bit of electronics that's in all TV's by their very nature and should b easy to get hold of... but the only readily available ones I've seen are multi-purpose pro convertor boxes that cost upwards of $200.
