ImgBurn is a real good DVD copying program. It can read a dvd into an ISO file and then burn that ISO to a blank. Is this what you mean?

a store bought dvd? or a dvd with the protection removed? and what are you wanted to do with the dvd? back it up? or just read it to your HD? etc.
you can use dvd decrypter to read it to your HD if the protection is removed

If the IOCTL is from user mode, Irp->AssociatedIrp.SystemBuffer contains a RAW_READ_INFO structure that specifies the starting disk offset, the sector count, and the track mode (XA or CDDA) for the read. Parameters.DeviceIoControl.InputBufferLength specifies the size, in bytes, of the structure, which must be >= sizeof(RAW_READ_INFO). Parameters.DeviceIoControl.OutputBufferLength specifies the size of the buffer to be read, which must be >= sizeof(SectorCount * RAW_SECTOR_SIZE).
If the IOCTL is from kernel mode, Parameters.DeviceIoControl.Type3InputBuffer contains a structure that specifies the starting disk offset, the sector count, and the track mode (XA or CDDA) for the read. Parameters.DeviceIoControl.OutputBufferLength specifies the size of the buffer, in bytes, to be read, which must be >= sizeof(SectorCount * RAW_SECTOR_SIZE).
it should be exactly the same to raw read a dvd as a cd, as long as you know wher and whereto (sectors and offset) you want to read
what happens is the driver writes the requested bytes directly (using DMA or PIO) to the buffer described by the MDL at Irp->MdlAddress.
then there are a couple of system calls..
IO..If the read is successful, the driver sets Status to STATUS_SUCCESS and Information to the number of bytes transferred. If the read is not successful, the driver sets Information to zero and Status to possibly STATUS_INVALID_PARAMETER, STATUS_INSUFFICIENT_RESOURCES, or STATUS_INVALID_DEVICE_REQUEST.
but you need to have dependencies available in an (include) ..Defined in ntddcdrm.h. Include ntddcdrm.h.
info will be in just about any modern C++ reference manual
heres the structure if you want it.. there should be exactly no difference (apart from sectors/offset between cd and dvd devices
typedef struct __RAW_READ_INFO {
LARGE_INTEGER DiskOffset;
ULONG SectorCount;
TRACK_MODE_TYPE TrackMode;
} RAW_READ_INFO, *PRAW_READ_INFO;
DiskOffset
Contains an offset into the CD-ROM disc where data will be read.
SectorCount
Contains the number of sectors to read.
TrackMode
Contains an enumerator of type TRACK_MODE_TYPE that indicates the type of the track mode.
YellowMode2
Indicates that CD-ROM mode should be used. This mode is used with read-only 120 mm Optical Data Discs (CD-ROM). XAForm2 Indicates that compact disc read-only memory extended architecture mode should be used. CDDA Indicates that digital audio information mode should be used.
Nothing here to see, move along folks.

I try to use IOCTL_CDROM_RAW_READ to read DVD, but failed. My vc++ code is following. Is there some wrong? Please help me.
typedef enum _TRACK_MODE_TYPE {
YellowMode2,
XAForm2,
CDDA
} TRACK_MODE_TYPE, *PTRACK_MODE_TYPE;
typedef struct __RAW_READ_INFO {
LARGE_INTEGER DiskOffset;
ULONG SectorCount;
int TrackMode;
} RAW_READ_INFO, *PRAW_READ_INFO;
#define IOCTL_CDROM_BASE FILE_DEVICE_CD_ROM
#define IOCTL_CDROM_RAW_READ CTL_CODE(IOCTL_CDROM_BASE, 0x000F, METHOD_OUT_DIRECT, FILE_READ_ACCESS)
BOOL RawRead(HANDLE h, int offset, int mode)
{
DWORD dwOutBytes;
RAW_READ_INFO rri;
char buf[2352];
BOOL ret;
rri.TrackMode = mode/*XAForm2*/;
rri.SectorCount = (DWORD)1;
rri.DiskOffset.QuadPart =(DWORD64)offset*2048;
ret = DeviceIoControl(h,
IOCTL_CDROM_RAW_READ,
&rri,
sizeof(rri),
buf,
(DWORD)sizeof(buf),
&dwOutBytes,
(LPOVERLAPPED)NULL);
TRACE("mode=%d, ret=%d, error=%d\n", mode, ret, GetLastError());
return ret;
}
I try all TRACK_MODE_TYPE, the output is:
mode=0, ret=0, error=1
mode=1, ret=0, error=1
mode=2, ret=0, error=1
