OK, so now I've replaced so far 42 capacitors in this VCR all of them of which had the green corrosion on the capacitor wire leads (the corrosion was on either one or both legs of the capacitors, but thankfully it wasn't bad enough to of eaten through the circuit board yet.)
I removed the Luminance and Chromanance board and replaced at least 2 dozen caps on that board alone (all of them had the green corrosion as well), and so far it seems that 99% of the capacitors I've replaced in this VCR were 47uF 16v capacitors with the other 1% being other values.
