Thanks, LIGHTNING UK
Space is correct and that for every giga 0.068 Gigabit lost, so the most you can put in an HD DVD-R 15GB is 14.04 GB.
I take the thread that goes on HD DVD for you to add the file separation program the following values, 14.04 and 27.96 gb gb that would be HD DVD-R and HD DVD-R DL some people still recorded in these formats.
