Page 1 of Goodmans GDVD124 Macrovision Hack?

Anyone know the Macrovision hack for this machine? Have tried the open draw press 7 then 4 method described in varying places but no good. It does take me to a menu where I can change the country code but there is nothing anywhere (first or second page) that says Macrovision. So I have been unable to change it from 1 to 0 as described elsewhere.
