Max welcome to the forum.
Your burner is an old model and doesn’t recognise the 16x discs you are using and in any case cannot burn them at 16x. The firmware has no write strategy for them.
New burners are relatively cheap and I would recommend that you purchase a new one, technology has moved on and there are a great number of advantages to this.

You could try some 8x media as some of this would be recognised by the latest firmware that’s available from here .

However a modern burner as suggested is by far the best idea & depending what country you’re in can be had very cheaply.

I’d suggest a Benq 1650 or Pioneer 111D as being a good investment.

Thanks weedougie and timc,will probably have to update my burner as you suggest.
Cheers,Max.

1.0C - thats the one you should go for.
