Bug in writing ISO's to DVD's?

There appears to a major bug in the StarBurn SDK for writing ISO images to DVD's.
I've primarily been testing with small text files and directory layouts. However when I put some .exe's and .zip's on a DVD as ISO they came out badly corrupted. Trying with some larger text files I see it's doing the sector offsets or something incorrectly as the text is their it just has some junk in it every so often.

Thanks,
Jory

Hi,

Please, tell me the way you are building the ISO-images. When the files are corrupted - it seems to the problem of mastering ISO file, but no the burning problem.

Hi,
I'm using code similar to this.

Code:

bool bLevel2 = true;
  m_ExceptionNo = StarBurn_ISO9660JolietFileTree_Create(
      &m_pISO9660JolietFileTree,
      m_ExceptionText, sizeof(m_ExceptionText),
      &m_Status,
      Callback_static, (PVOID)this,
      TRUE,
      FALSE,
      bLevel2 ? TRUE : FALSE,
      FILE_TREE_JOLIET);

  void *pRoot = NULL;
    pRoot = StarBurn_ISO9660JolietFileTree_GetRoot(m_pISO9660JolietFileTree);

  m_ExceptionNo = StarBurn_ISO9660JolietFileTree_Add(
        m_pISO9660JolietFileTree,
        m_ExceptionText, sizeof(m_ExceptionText),
        &m_Status,
        (char *)path.c_str(),
        folderName.length() == 0 ? NULL : (char *)folderName.c_str(),
        FILE_TIME_LAST_WRITE,
        &pRoot);

  m_ExceptionNo = StarBurn_ISO9660JolietFileTree_BuildImage(
      m_pISO9660JolietFileTree,
      m_ExceptionText, sizeof(m_ExceptionText),
      &m_Status,
      0,
      8,
      FALSE,
      (char *)VolumeSetName.c_str(),
      (char *)PublisherPreparerName.c_str(),
      (char *)ApplicationName.c_str());

...

          exceptionNo = StarBurn_CdvdBurnerGrabber_TrackAtOnceFromTree(
                          CStarBurnCDImageBurnerGrabber, 
                          ExceptionText, sizeof(ExceptionText), 
                          &Status, &CDBFailureInfo,
                          m_Image->GetImagePointer(),  // m_pISO9660JolietFileTree
                          FALSE, // TRUE -- MODE2/Form1 vs FALSE -- MODE1, would be IGNORED for RAW images
                          m_bTestWrite ? TRUE : FALSE,
                          m_bNextSessionAllowed ? TRUE : FALSE, // TRUE, // Next session allowed
                          WRITE_REPORT_DELAY_IN_SECONDS,
                          BUFFER_STATUS_REPORT_DELAY_IN_SECONDS);

Thanks,

Your code seems to be fine. Now we'll need exact directory structure put somewhere on ftp, add/remove actions performed with it. To reproduce, confirm (maybe) and fix (if confirmed) the issue. You seems to be the first one reported broken images so far...
