Max capacity for dvd-r?

[X-treme]

When ripping a movie, what is the max capacity one can go up to?

I notice that with instant copy you can 'adjust' the limit to whatever size you want up to a certain limit (4.37gig). Let's say I push it to 4.5- 4.6 gig, does that value include closing off the dvd-r? If not, how much is needed to 'close off' the media?

Thanks

It is advisable to utilize only 96% of available DVD capacity for “user data”. The 4% overhead is required for menu graphics, navigation information and a little safety cushion for manufacturing tolerances.
