Bluestacks(beta-1) is very old version, so this video was deprecated from now.
But you can download latest version from Bluestacks home page ( http://www.bluestacks.com ), Google Play Service is supported by default. Thanks
Incompatible with other application(s) using the same share user ID, error fixed
