Bug ID: 39266
           Summary: Microsoft Wine Guide does not play video files with
                    .cp extension
           Product: Wine
           Version: 1.7.51
          Hardware: x86-64
                OS: Linux
            Status: NEW
          Keywords: win16
          Severity: normal
          Priority: P2
         Component: winmm&mci
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

Currently while trying to detect a media type (video, audio file, cd audio)
wine assumes that when the file comes from a CD (GetDriveType() == CDROM) the
path must be a cd audio file.
> From dlls/winmm/mci.c:

1794 /* type, if given as a parameter, supersedes file extension */
1795 if (!strDevTyp[0] &&
1796      MCI_GetDevTypeFromFileName(lpParms->lpstrElementName,
1797                                strDevTyp, sizeof(strDevTyp))) {
1798     static const WCHAR wszCdAudio[] = {'C','D','A','U','D','I','O',0};
1799     if (GetDriveTypeW(lpParms->lpstrElementName) != DRIVE_CDROM) {
1800         dwRet = MCIERR_EXTENSION_NOT_FOUND;
1801         goto errCleanUp;
1802     }
1803     /* FIXME: this will not work if several CDROM drives are installed on
the machine */
1804     strcpyW(strDevTyp, wszCdAudio);
1805 }

Relevant log part:

Naturally this fails later because mcicda fails to read the TOC from the CD and
gives up.

Windows plays the videos just fine so I guess wine should try to open the file
and guess a file type.
