Pioneer 107d media problem and burn speed

I have had the pioneer A06 for a while and had no problems.
I have just bought the 107d and flashed it to the fw 1.10.

I am having trouble with my machine locking up when I have inserted some media, and some other 4x media that I have been useing with my A06 for some time without any problem is taking 30-35 minutes to burn.

Any ideas ???

:confused:

What IDE drivers do you use?

Is DMA enabled?

The drive may have troubles with some cheap media. (Yes the 107D is pickier than older pioneer drives).

I have now sorted the problem
Thanks for replying.
