The Most Compatible DVD Format: DVD-R
jbridges writes "CDR-Info tested eight types of media (two examples of each media type) using five different recorders, then tested compatibility in twenty-seven standalone DVD players and twenty DVD-ROM drives.
They determined that DVD-R is clearly the most compatible DVD recording format on the market. To assess the compatibility level of DVD Formats they created video content on a DVD writer using DVD-R/RW and +R/RW media. These discs were then played back in other DVD players and DVD-ROM drives -over a 1,000 combinations of drive, media and player were tested."
All I can say is DUH.
All of us who have been mastering DVD's for clients have known this cince 1999.
Do not look at laser with remaining good eye.
