Which DVD writer do I have?

Nero allows me to enable “Seamless Link”.
So it’s a BenQ? (http://www.benq.com/news/seamless_link.html)

It can only write +R(W) but is (officially) capable of reading double layer discs?!

Uh as far as I know every DVD drive can read double layer, whether it can write it or not, if that is what your asking

Additional information:

  • it’s built in a laptop
  • the specifications say it can handle +R @4x, while InfoTool only reports 2,4x

Just found something of interest: http://forum.rpc1.org/viewtopic.php?t=27403

So it seems to be a NuTech.
