Well this is the method that has been tested and works....
1. Run REGEDIT
2. Find HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices\
3. Rename the DVD drive that is real and add the drive letter of daemon drive
as shown in example below:
\DosDevices\E.F: where E is my real DVD drive and F is the fake one.
4. Note that registry re-adds the correct drive labels on rebooting pc, other than that runs Yasu v1.4 and it works a treat.
