NO not rewritable, once only
Using HP DVD +R Dual Layer DVD and same but Memorex Brand.
Both 8x, 8.5 GB, 240min, which seems standard for a dual layer.
After creating the disc, it seems faster to use a copy dvd software. The software both from CyberLink and Roxio sees the disc as being open on the dual layer disc, a single layer shows closed after the PD 11 burning.
The disc plays fine on the Blu Ray player for the AVCHD created disk just that it shows being open and not a closed disc. So I find it odd that PD 11 does not close it after the burning process. I have sent support an inquiry on this matter since I did not find anyone esle that had posted such a question as this one.
