CD burner only burning at 2x

[LockRobster853]

Since I've put my 12x burner in a new machine, Nero refuses to burn at full speed. It just says "Can only write at 2x instead of 12x to current disc".

I know it's not the media or Nero cos I used both in my old machine. I'm thinking maybe it's the IDE cable but I've swapped it out with others and get the same thing.

Any ideas?

Thanks

Check to see if the drive is stuck in PIO mode instead of DMA.

The channel is set to DMA if available. The burner is in DMA mode and the slave DVD drive is in Ultra DMA mode.
