Yeah! I've found a solution to avoid the problem of the quotes. This script works fine:
Code:
set path=%PATH%;D:\BD3D2MK3D\toolset
start /low BlockSleep.exe __ENCODE_3D.cmd
It's strange anyway. Perhaps you can find a solution to avoid the quotes bug from within BlockSleep itself, although I don't need imperatively a fix to use it with BD3D2MK3D.
