My DVD RW drive will only burn at x2 Speed

Essexdelboy

I have got a NEC DVD RW ND 3520A, which is capable of burning at 16 x (I think) and I am using x4 discs, but for some reason I can only burn at x2 speed, which is taking an absolute age. The discs work perfectly on my dads machine (at 4x speed and using the exact same model DVD RW drive, so I know it is not them).

I am using DVD decrypter or Nero 6 to burn my DVD’s and I am running on Windows XP SP2.

Can anyone help?

Do I have to change some settings on my drive or via my device manager etc?

Any suggestions would be most welcome.

Thanks Browntoa i wil give it a try

But the link to the firmware download is invalid, do you know of anywhere else i could find it?

Look at the IDE channel properties in Device Manager and check it is in DMA and not PIO mode.

I burnt the DVD but it still took 29 minute (approx 4.7 gb). So i will try doonhammer's suggestion, but does anyone else have any ideas?
Have I downloaded the wrong firmware?
Should I download official NEC firmware? (if there is such a thing!)

i tried Doohammer's suggestion and my drive is DMA enabled. Can i try anything else?

some evaluation (demo) versions of software cripple your burn speed, could be that.

check the DVD's are not rated at 2X ,they wont burn faster than their rating.

they are definately 4 speed, should i try another firmware software for the drive? will this rectify the problem?
