The new High speed DVD RAM media cannot be as frequently overwritten as the older versions. Goods media for 1X, 2X and 3X still for 100.000 overwriting procedures specified, are it with the 5X and 16X-Medien "only" 10,000 overwriting procedures
Only 10,000 times.. its still better than -RW and +RW though.
