If the VGA has TV-Out signals (you would have to check the spec to
find out) then you could use something like
http://www.ebay.co.uk/itm/1-5M-VGA-to-3-RCA-COMPOSITE-VIDEO-CABLE-PC-TV-LAPTOP-/151000907450?pt=UK_Computing_CablesConnectors_RL&hash=item23285afeba
to convert to composite video then one of the cheap video capture
devices  to capture it.

without the right keywords was probably not successful.
