How our DVDs and DVD-Rs Differ
Customers who purchase programs in the NG DVD-R Library will receive a non-interactive, play only disc. There is no chaptering information on these DVDs, but there are chapter marks approximately every five minutes, which make it easy to fast forward through a program. The DVD-R format provides the digital video and audio quality you expect from all of our DVDs.
NOTE: The NG DVD-R titles are not closed-captioned. We apologize for any inconvenience this limitation may cause.
