I finished to re-align all the four captures; I changed their ratio on median&average script; I lowered the sharpening (maybe too much?)

If someone is just curious to see some scenes - two with no (apparent) DVNR or IVTC problems, just take a look... here you are four test clips I uploaded on YouTube - as they are short, 8 seconds, and without audio, maybe they will stay there for a while... ;-)

Just don't forget (as I did...) to set the quality at 720hd... and don't forget they are taken from laserdiscs!
