Hello there,

I’ve got a NEC/Optiarc AD-7543A Slimline DVD Burner with the following specs:

DVD +R: 8x max.

DVD-R: 8x max.

DVD +RW: 8x max.

DVD-RW: 6x max.

DVD-RAM 5x max.

DVD +R9: 4x max.

DVD-R DL: 4x max.

CD-R: 24x max.

CD-RW: 24x max

I’ve bought some “Intenso DVD+R 4,7 GB 8x” but I can only burn at max. 4x.

Nero CD-DVD Speed says about the DVD+R:

Disktyp: : DVD+R

Book Type : DVD+R

Hersteller: : Optodisc

MID : OPTODISC OR8 000 (00)

Schreibgeschwindigkeiten: : 2.4 X - 4 X

KapazitÃ¤t : 4.38 GB

Does anyone have an idea/solution for this problem? I think the MID is not correct, what do you think?

I’ve searched for a firmware upgrade but without success.

Thank you very much!
