SLOW Burning with LG GCE-8523B

[grouch]

Hi,
I have this problem where my CD-RW churns out 700MB CD-R's in 6-7 minutes when I select it to burn at 52x. At this rate, my old 8x burner can compete with 3 minutes difference.
I typically burn .bin and .cue (cuesheet tells Nero to burn the .bin file).
I read somewhere that DMA needs to be on to utilize the full potential of this drive, but I don't know how. Help...
As well, when using Nero 6 Ultra Edition, the buffer for the recorder occasionally dips from 90-99% to approx 50% and jumps back to 90-99%. Is this affected by something that I can change too??
Thanks.

Thanks a lot....I turned on the DMA and attached my DVD-ROM too and it still burns blazing!!! Thanks for the info...

Just wondering, I tried to copy 700MB XViD to my hard drive (tried to transfer to both my Master and Slave) and both took 8+/- minutes. I know that it only reads at 40x max, but is that time normal??
and my OS is WinXP SP1
