I have stumbled upon the following problem : I can burn Double Layer discs with my plextor PX-716A using Nero 6.3.1.17 without problems.
However, when I switch back to single layer discs after burning a double layer disc, the first single layer burns ok, but the disc is no good : I get incredibly high PIE values for the first 10% of the disc, after which the PIE value falls back to normal values. It is actually visible on the disc : there is a different colored ring which spans about 10% of the disc.
The next single layer disc burns without problems.

I have seen this happen twice now, does anyone know if Nero has a problem with layer switching or something ?
