Windows 7: DVD Burner showing error when burning dvds

OS: Windows 7 Ultimate x64

Hi guys. I am not sure if the problem with my DVD burner is a software related one or a hardware related one. I am using HL-DT-ST DVDRAM GH22NS70 SCSI CdROM device. Of late, most of the times when I am trying to burn a disc, it shows Program Memory Area Update Failure. The errors are random. At times I can burn 2-3 discs before the error pops up. At times it happens during burning the first disc. The type of files I am burning also has no effect as the error occurred as I attempted to write various types of disc. I sed ImgBurn and Nero but the problem persisted. What is the problem and what do I need to do to solve this?
Thanks in advance.

I am just curious to know what brand media you are using.

Moserbaer and Verbatim.

OK.Thanks for the info. I was just trying to see whether a sub-standard media could be the cause. Since then I have come across a reference that this error can happpen even with the best media.

So any idea regarding how to troubleshoot the issue?

OK, In my limited web search - limited by time available - I have gathered some info on it but none the wiser to suggest a solution at the moment.
