IsoBuster 4.4 with HDD DVR Video recorder support released!

June 17, 2019

I'm very happy to announce the release of IsoBuster 4.4.

We did a considerable effort to implement a plethora of HDD Video Recorders. Not only did every brand use its own proprietary format, almost all families or ranges of recorders for a brand were different as well, so it was quite the effort. More than 50 different situations were encountered and implemented. As a result IsoBuster shows and allows to fully extract the files and folders from these recorders with focus on the mpeg video recordings, their names, time and date etc.

Also check this page with videos showing you how to extract the video from several supported HDD Video Recorders.

But that is not all. As usual there are plenty of other improvements, fixes and new functionality as well.

Changes / New:

  • Support for Toshiba HDD recorders (RD-XS32, RD-XS52, RD-XS34, RD-XV34, RD-XS54, RD-XS35, RD-XS55)
  • Support for Pioneer HDD recorders (DVR-510, DVR-520, DVR-530, DVR-630, DVR-531, DVR-533, DVR-633, DVR-540, DVR-543, DVR-640, DVR-450, DVR-550, DVR-650, DVR-555, DVR-460, DVR-560, DVR-660, DVR-940-HX, LX60D, LX61D, LX70)
  • Support for Sony HDD recorders that mimic (or under the hood are) Pioneers (RDR-HX750, RDR-HX780, RDR-HXD1090)
  • Support for Panasonic HDD recorders (DMR-E80H, DMR-E100H, DMR-E85H, DMR-E95H, DMR-E96H, DMR-E500H, DMR-EH50, DMR-EH60, DMR-EH55, DMR-EH56, DMR-EH57, DMR-EH75V, DMR-EH75, DMR-EH58, DMR-EH68, DMR-EH59, DMR-EH69, DMR-BS750, DMR-BS850, DMR-BS780, DMR-BS880, DMR-BS785, DMR-BS885) (MEIHDFS)
  • Support for Philips HDD recorders (DVDR-3575H, DVDR-3576H) (HDDFS)
  • Support for Magnavox HDD recorders (H2080MW8, H2160MW9, MDR-513H, MDR-515H, MDR-533H, MDR-535H, MDR-537H, MDR-557H) (HDDFS)
  • Support for RCA DRC8030N HDD recorder
  • Support for LiteOn HDD recorders (LVW-5045, ILO DVDRHD04)
  • Support for Medion MD 81888 HDD recorder (which is really a LiteOn under the hood)
  • It is entirely possible that other Sony, Medion, LG or other brand DVRs can be listed here as well if they are re-branded models from above list. Not the Sony RDR-HX900/HX1000 recorders however because they have been proven to encrypt the video, so there is no point trying. Following Sony RDR models are also suspected to encrypt the video: 510, 710, 715, 717, 910, 919, 1010, 520, 525, 720, 722, 725, 727, 820, 825, 920, 925, 1020, 1025, 730, so recovery from them is probably not possible
  • The IBP/IBQ Image file manager can now Import and Export lists of sectors for super easy engineering
  • Option to find and enumerate optical drives with media that is not CD, DVD, BD media with tracks and sessions, such as MO and PD media that contains partitions and generic non-optical file systems
  • Support for the Atari ST *.st image file


  • Ability to clone to a device with different block size. For instance from a virtualized 2K device to a 512-byte device
  • Added "Offset:", "StreamCnt:", "ExtentCnt:", "MemberCnt:" and "UnreadableCnt:" to the Search bar functionality
  • Improved 'ESC' key use during dialogs that have a default action defined
  • The 'F5' key now always refreshes the content, no matter what IsoBuster object is selected (Tree or ListView or ...)
  • 'F5' or the Refresh button clicked during a 'Find' will ask if Find can be interrupted or not
  • 'F5' or the Refresh button clicked when recovered file systems are present will ask for confirmation
  • Ctrl-Shift 'D' Toggles CD/DVD Open/Close tray or Image file close
  • Allow more custom defined export lists (20 instead of 10)
  • Implemented support for a fragmented DVD-VR's MNGR IFO file
  • Do not consider a MS virtual CD/DVD drive an old style SCSI device (affects type of SCSI commands being used)
  • Changed the Manual retry approach on erroneous sectors to keep the dialog up while retrying
  • Small DVD-VR vs. HDD-VR detection improvements
  • Improvement for bad behaving drivers that report incorrect byte alignment requirements. Seen on Tablet PCs with 32GB eMMC
  • Implemented Tree export commands {%ONLYREADABLE}, {%ONLYUNREADABLEBLOCKS}, {%ONLYSELF}, {%ISO8601(D)}, <%READABLE> to the file export functionality
  • Reports can now use <%%(F)> and <%TOT%(F)> to show 2 digits behind the comma for the percentage of readable blocks
  • Implemented Tree export commands {%BLOCKS}, {%BLOCK} and <%BLOCKLOOP> to the file export functionality to be able to build lists of blocks per object
  • Implemented Tree export command {%BLOCKSINRANGES} to the file export functionality to display ranges rather than a single address on every line (when exporting {%BLOCKS})
  • Implemented Tree export commands <%IF>, <%DO>, <%ELSE> and <%ENDIF> but also <%CI>, <%WC>, <%RE>, <%=>, <%>>, <% <>, <%>=> and <% <=> to the file export functionality to be able to generate conditional text based on the object's properties
  • Keep track of GEMDOS created FAT 12/16 FS via the file system <%CREATOR> field and the file system Properties dialog
  • Give (debug) *.ibadr and *.ibdat files a unique name so that files don't get overwritten all the time.
  • Improved breadcrumb control GUI when using the classic theme
  • Improved breadcrumb control functionality on Windows 2000
  • IsoBuster can allocate even more memory now (on 64 bit systems) and is easily able to deal with millions of objects
  • Plenty of other improvements, changes and re-writes in the core code / engine, as this is a living project and to deal with the ever growing new functionality
  • Various other GUI improvements


  • Make sure command line parameter /d:* works again
  • Fixed the FAT file system's use of the FAT-table (and because of it the ability to find extents) when the device blocksize is 512 and the FAT-native blocksize is 4096 (should actually not be a real life situation, but encountered during development)
  • Fixed high contrast (for the vision impaired) for all OS and use the best color for the Breadcrumb control
  • Fixed a rare crash when scanning for lost UDF files and folders
  • Fixed a hard to reproduce hang when exploring folders in TreeView while a Search was in progress that also wanted to expand the same folder
