Golden,
That's double sided.Each side approx 4.7 GB
You have to flip when recording.

Yes, you must turn 9.4GB DVD-Rs. They work great if you have a Sony DVD that can flip discs automatically!

Commercial DVDs are pressed and bonded. There is a great UK site that describes the process for all DVDs (including DVD-18s like Gods and Generals):

Commercial DVD's are pressed not burned.

DVD-9 DVD-R's are unlikely to be with us in the forseeable future - creating a media and a mechanism where you can burn one layer through another without destroying that first one in the process at such a narrow difference of focal length is not an easy task.

Plus the resulting burn has to be reliable and compatible (the reflectivity of two organic dyes is not going to be even close to the silicon alloy usually used in pressed discs), and bit management is an issue too - the second layer by design has to have less data on it than the first, and the complexity of an authoring program on its own that can take this into account and create a complaint disc means £££ / $$$.

Don't forget the glue holding the two layers together can't be affected by the burn process either - the science between the glues used in DVD's is a nightmare and covered by several patents as it is...
