            Bug ID: 37767
           Summary: IOCTL_DVD_READ_STRUCTURE expects the wrong size of
                    output buffer for some requests
           Product: Wine
           Version: 1.7.33
          Hardware: x86
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: ntdll
          Assignee: wine-bugs at winehq.org
          Reporter: erich.e.hoover at gmail.com
      Distribution: ---

IOCTL_DVD_READ_STRUCTURE expects all replies to be of
sizeof(DVD_LAYER_DESCRIPTOR), though the actual reply is dependent upon the
request.  This prevents the application "VUDUToGo" from identifying DVD discs
for converting to digital copies.

The problem can be fixed by expecting the correct size reply from the different
request types:
