SecuROM Error code 1000 means that your optical drive didn't perform a precise Data Position Measurement - which is needed for Securom CDs/DVDs, or that your optical drive doesn't check the disc with a stable speed to authenticate the Securom sector deviation, or that you simply forgot to activate RMPS emulation in Alcohol's Emulation options before inserting your burned copy.
Provided that you've created the image with the correct Alcohol profile (SecuROM) and that RMPS emulation is activated, you can try to change your drive's speed with tools like CD Bremse (CD Throttle) or nero DriveSpeed.
Maybe then it works.
If you can't get the burned copy to work at all you can try to mount your image in Alcohol's virtual drive.
P.S.: would you please upload your MDS file so i can check whether it can function at all
