My communications with Sarah Kepler Supervisor of Sony Support (USA) at Sony Electronics

I hope Sony will be able to fix the issue with setting the clock (since an update isn't coming from the assigned TV station) on the DHG-HDD250/500 DVR. If Sony could provide new firmware to set the clock manually would be a great help to all of us who have the DVR. Is this possible?

I believe we have a fix now. The Recording Time Calculator app is intended for Sony customers who own a DHG-HDD250/500 Digital Video Recorder, and wish to schedule manual recordings.
It is still possible to schedule manual recordings even without Guide data. Using the Recording Time Calculator app, you can enter the DHG-HDD250/500’s system clock time, and the start/end times of the program you wish to record, and this app will calculate the times to enter into the manual recording menu on the DHG-HDD250/500.
To schedule a manual recording:
• Access the manual recording menu on your DHG-HDD250/500, by pressing the “REC” key on your remote control for 2 seconds.
• Enter the current system time into the Recording Time Calculator.
• Enter the start time and duration of the program you wish to record on the Recording Time Calculator.
• Press the “Calculate Times” button.
• The Recording Time Calculator will use an offset to calculate the values to be entered into the start and end times on the recording menu.
• Enter these values into the DHG-HDD250/500’s recording menu and select the “schedule recording” button.
I hope this helps!

The DHG-HDD250/500 was released in early 2005 and since then there have been at least a couple of firmware upgrades. The latest version 1.2.21 released 04/10/2009 was made to specifically address the use of the new digital channels to work properly with the TVGOS data and setting of the date/time. All of the DHG-HDD250/500 users were delighted when Sony made this upgrade available.
Ever since Rovi pulled the plug on providing data to the many products out there that used the data, created a lot of unhappy users. Sony's attempt to provide a way to be able to record TV programs with the "Recording Time Calculator" is an inadequate interim solution since many of us do not have an android tablet or smartphone to use this app. A similar solution was proposed by a AVS Forum member WS65711 back on 08/17/2011, see:
I would think that the wizards in Tokyo (Sony Engineering) should be able to come up with a permanent fix by altering the firmware to provide a way to set the date/time in the setup menu. If (ROM) space is an issue, there are items in the setup area that can be eliminated (TVGOS, ZIP, etc.) to make space for the setting of the DVR's real time clock (RTC). If that's not possible than Sony should release the source code (Linux) to those who could provide a way of setting the date/time.
With that, the DHG-HDD250/500 DVR users would be eternally grateful to Sony.

I'm sorry Ken but this is the current resolution to this issue. I wish there was more we could do.

Sarah - I'm also sorry, if this is the best Sony can do, I'll need some convincing before I ever consider purchasing another Sony product. I expect (and others do too) better support than this when making a high-end purchase.
