I have the following instructions to follow:

Create the Update Disc

1. It is important to use a good quality branded blank CD-R disc or completely erased CD-RW disc.

2. Create the update disc by burning the file to a CD-R or CD-RW disc.

3. Burn the file to the disc using disc-at-once mode (2x Speed) and ISO 9660 CD-ROM file system format. (The player will not recognize the update disc and the update cannot be performed if the file is not burned correctly to the disc.)

4. Make sure that the disc session is closed / the disc is finalised.

This is an update disc for a CDJ800MKII

I have Nero 7 and XP.

I have no clue how to burn the disc the way it wants, its beyond me... Any help would be much appreciated thanks.

The image you have downloaded will be in ISO 9660 format so you don't need to worry about that. I have Nero 6 and I hope the process is the same, but I'll tell you how to do it for 6 and hopefully you'll be able to figure it out for 7.

Start Nero Express
Select the Disc Image or Saved Project option.
Locate and select your ISO file.
Choose 2x write speed from the drop down menu.
Burn the disc.

Hope this helps

Thanks for your reply.

There doesn't seem to be an option to change write speed on Nero Express.

I tried to do it on Nero Burning Rom but 8x wrtite speed was the slowest available, 2x was not an option which was frustrating.

Is the any other way of getting around this problem?
