Firmware and SoftwareEdit

The firmware is the operating system of the DVR, and is produced by Anand Enterprises with options that can be enabled / disabled by your local cable provider / MSO. The firmware is roughly like the BIOS and core code of your computer's operating system. It has the programming to access the hardware, read and write files and video streams to/from the hard drive, and other basic functions.

The software is the user interface that you see, and typically handles the scheduling, program guide, PPV/VOD and many other complicated features. The software used depends on your cable system. There are several current suppliers. i-Guide is currently the most common.

The Interactive Programming Guide (IPG) software can be provided by i-Guide (Comcast, Time Warner, Adelphia, Mediacom, Brighthouse Communications, Passport Echo] (Cox, RCN, Service Electric Wilkes-Barre), or Microsoft TV Foundation Edition] ("MSTV Foundation Edition" or MSFE) (Verizon, Comcast in WA state).

i-Guide is a product of GuideWorks, LLC], an IPG development group formed in August 2011 by Comcast Corporation and Gemstar-TV Guide International]. The programming information is provided by the television network to GuideWorks, which supplies the data to cable providers for use with the i-Guide.

Note: You cannot update/change the firmware, software, or IPG versions on your particular box. Updates are pushed out by your local cable provider/MSO based on a variety of considerations, including maintenance windows, update schedules, and the software available on their own equipment.

How To Check Your Firmware and Software Versions - Main MenuEdit

Press the "Menu" button TWICE on the remote to get to the "Main Menu". Arrow down if necessary and select the "Setup" menu on the bottom left. Arrow down once and select the second option, "Cable Box Setup". Arrow down to the bottom and select the "Select to display" button. The text second down on the left is "S/W Ver". This is your software version. The text sixth down on the right is "Firmware". This is your firmware version.

How To Check Your Firmware and Software Versions - Diagnostic MenuEdit

Turn off the box (press POWER on the remote). Immediately press OK/SELECT. Press it again if the display (black text on white background) does not come up within a second. DOWN ARROW to "d08 CODE MODULES" and press OK/SELECT. The firmware version and build date are listed at the top, e.g., "Platform Built: Version: 16.20 Sep 1 2011 15:06:09". In the middle of the page, there is an "Object" column and a "Ver" column that lists your firmware and software versions, e.g., Firmware: TC_OS_ED 16.20 IPG Software: TV_Guide 74.53 VOD Software: A231_VOD 23.45 To exit the menu press POWER twice. The unit will exit the menu and turn back on.


The latest firmware and software, and their respective versions, will vary by cable company and your local area (pushing out firmware and software versions is controlled by your local cable provider). The "available" date only represents a point in time when it was known to be available as the latest version in any given cable market. The date is in ISO Year-Month-Day format.

Some features, such as the 30-second skip, are options that can be enabled or disabled by the cable provider. Sometimes, they may accidentally disable the 30-second skip by mistake. Some cable providers replace the 30-second skip with a 3 minute skip, designed for quickly skipping commercials.

  • Available Date: 2006-09-20
  • VOD Version: A231_VOD 23.45
  • Bugfixes:
    • "MUTE" bug during scheduled recordings. Comcast: "The DVR mute issue has been resolved. Pressing any key except mute and volume up or down will unmute a muted recording." Note that "MUTE" is now only displayed on-screen at the moment the audio is muted, not continually while muted. Also, canceling the mute will also cancel the automatic power off when the recording ends.

    • Includes features of 73.44, plus...
    • 30-second skip feature is re-enabled on Comcast.
    • Fast-forward and rewind are much faster.

    • "Additional HDMI Settings" page on the User Settings Menu, offering a DVI or HDMI output setting, wtih Color Space and Audio Output settings for HDMI.
    • Pressing the Menu button, then going to the Home icon now goes to Comcast Central instead of Main Menu (which can still be accessed directly by pressing the Menu button twice).
    • If a manual recording covers multiple programs, all will display a record icon in the guide.
    • Multiple Favorite lists can be created.
    • When displaying the guide (full or mini), pressing FAV will only display your favorites.
    • The DVR %Full number no longer includes the 3% used by the buffer.
  • Lost features:
    • Manual recordings that cover multiple programs no longer display divider ticks on the time bar. The individual programs no longer list their actual running time on the info screen, but list the entire recording time instead.
  • New bugs:
    • The graphic overlay doesn't always cover to right side of the 4:3 screen. This appears to be somewhat based on the length of the channel number and name.
    • Canceling a repeating manual recording after it starts will cancel all future recordings. The older software would just cancel the current one, but not affect future scheduled recordings.

Current HDDs Used in Motorola DVRsEdit

DCT-6412 Phase I and IIEdit

The DCT-6412 Phase I and Phase II use a standard SATA drive.

  • Seagate ST3120025ACE (CE=Consumer Electronics version of ST3120025A.)
  • Maxtor 4R120L0

DCT-6412 Phase IIIEdit

The DCT-6412 Phase III uses a standard SATA drive.

  • Maxtor 6L120M0
  • Seagate ST3120026AS
  • Seagate ST3120022AS
  • Seagate ST380817AS


  • Seagate ST3160023AS
  • Seagate ST3160021AS
  • Seagate ST3120827AS
  • Seagate ST3160212SCE


  • Seagate ST380012A

The models mentioned below need to be verified, as the 6208 is a modified 6200, and is IDE, not SATA.

  • ST380013AS
  • ST380011AS
  • ST340111AS
  • ST340014AS

All Other ModelsEdit

Not yet tested and verified.

Recording Capacity vs. HDD SizeEdit

  • On the 160GB drive the data partition is 147,581MB. At 5.6GB/hr, it would hold 26.3hrs.
  • On the 120GB drive the data partition is 109,900MB. At 5.6GB/hr, it would hold 19.6hrs.
  • The 160GB drive has 34% greater data capacity.

Hidden F/W FeaturesEdit

  • F/W version 12.31, found in the DCT6412 III and 3412 I, harbors an undocumented ability to recognize a 160Gb HDD.
  • Maxtor (Quick View series) and Seagate (Barracuda 7200.7 Serial ATA) HDD brands are used interchangeably in the DCT DVRs, so far three brands have been used in an operability test, done by four separate DCT DVR owners. One was a Western Digital (WD1600JS - SATA I Jumper enabled), two were Seagate, and one was a Samsung Spinpoint P 160GB. After installation, the HDDs were recognized and successfully formatted to 160Gb in all STBs.

Credits & DisclaimersEdit

  • Technical information credit goes to Cavu, who did a great deal of research on the numbers.
  • The highest capacity drive that was talked about and then implemented from Motorola is only 500Gb.
  • A 300Gb HDD was used in one of the boxes. Once formatted, only 160Gb was allocated. So, it would seem that no larger HDD will work beyond that, and the S/W & F/W are not intuitive or adaptable to anything higher than 160Gb.
  • As of software version 75.59 a25p2-2.S1.r-8 and firmware version 16.53, the SATA, and USB ports have still not been enabled. The HDD size is still limited to 160Gb.
  • It is important to note the testing took place in Canada (on cable systems utilizing i-Guide), where subscribers buy and own their STBs, unlike in America where they are rented from cable providers. Installing or replacing parts (modding) may violate the manufacturers warranty. In the U.S. if the modded box isn't returned to the CC in a pre-mod state, at the very least you will be forced to buy the DCT back for full market price.
