Is playback of recorded 4.7 GB DVD-R media possible on all DVD-players and ROM drives?
It should be possible to achieve playback on many DVD players and DVD-ROM drives, barring some exceptions. Formats released by the DVD Forum are specifications for the MEDIA only. Although a recorded DVD-R disc falls within the same specifications as DVD-ROM (DVD VIDEO), because the formats are media-related ONLY, support will be entirely up to the hardware maker.According to a study conducted by media makers, DVD-R media is capable of playback on many players with some exceptions. Examples where playback may not be possible: Since the DVD-R Book was released AFTER the DVD VIDEO Book, 1st generation DVD-VIDEO players may have problems reading DVD-R media. Also, some SLIM DVD-ROM drives and portable DVD players have been known to have problems reading DVD-R media. It is recommended that when the size of data is such that it will fit on a 3.95GB DVD-R then 3.95 blank media should be used. This will ensure the widest compatibility with various brands and models of DVD Players and DVD-ROM
