LG HL-DT-ST DVD RAM GSA H55N burn problem

[qanda]This thread is about the LG GSA-H55N. Click here to see full specs[/qanda]Hello!
. Suddenly since January my LG HL-DT-ST DVD RAM GSA H55N drive seems to burn DVDs at a very slow rate, taking nearly an hour to burn a 4.7Gb DVD. At first I thought it was the burning software Nero so I used Imgburn but still it refuses to burn faster than 1x.
Also, I checked the drive and it is in DMA mode.
Please help!
My OS is Windows XP Service Pack 3.
:sad:

Which DMA mode?
Please post a burnlog.

I started having the exact same problem like two weeks ago, all of the sudden my H55N started burning painfully slow, and not only that, it’d make my entire computer slow.

I fixed the problem by upgrading the firmware (from 1.05 to 1.06).
