problem as I see it the lesser devices only support the worst possible connections does the laptop allow cloning of outputs? if it does you could use a HDMI distributer I am guessing you could piggy back 1 in to 2 out which are readily available then svideo to the lesser devices in clone mode.
If it does not offer clone any single solution is only going to offer poor quality to match out with your lesser hardware
