As the subject already told:

Is a double-layered DVD ALWAYS double-sided ? Or are the single-sided double-layered DVDs ?

In other words: If I have a double-layered DVD do I have to flip the DVD on the back side to access
the remaining 4.5 GB ?

Furthermore if there are single-sided, double-layered DVDs (=with capacity close to 9 GB):
Do these DVDs exist only pre-burned from manufacturer or are there writable (e.g.DVD+RW)
single-sided doble-layered buyable DVDs as well? (I have never seen such DVDs)
