Sony firmware question (DRX-510UL)

Regarding Sony’s DRX-510UL, but this is probably relevant to other Sony DVD burners:

The firmware update instructions on Sony’s site read that before executing the firmware update (1.0D) you must:

  • uninstall any packet writing software, such as (DLA, DirectCD, etc. from the PC…

I usually follow directions, especially when messing with firmware, but I really don’t want to uninstall those components if it’s not absolutely necessary. For others who have flashed Sony drives, is it really necessary to uninstall DLA & DirectCD before proceeding?

Thanks -
