After a good meal and some rest I found out that m_RealDevice and 
m_DevicePath are accessible in the MythCDROMWindows class (as in all the 
other classes), so I can now create my handle to the optical drive like 
this:

const char *devicePath = strncat("\\\\.\\", m_RealDevice.toLocal8Bit(),2);

HANDLE hDevice;

return hDevice = CreateFile(
     devicePath,
     GENERIC_READ,
     FILE_SHARE_READ | FILE_SHARE_WRITE,
     NULL,
     OPEN_EXISTING,
     0,
     NULL
);

Now off to drink a beer!

Cheers,
