新的DVD Identifier 3.3版能夠辨認Dual Layer空白片跟16X DVD+R,下載吧!!
Changes in latest version (V3.3) - released June 1st, 2004 :

Support for double-layer DVD+R (DVD+R DL) and 16x DVD+R discs.
Through the use of an internet-updatable database the Manufacturer IDs are now displayed together with their full manufacturer name (e.g. 'MCC' is now also shown as 'Mitsubishi Chemical Corp.').
Support for DVD-RAM.
Added a warning indicating that 8x DVD-R discs cannot be detected. Even though 8x detection code is in-place no drives currently report sufficient 'write strategy'-information to make this work. Note that although 8x detection by analysis of the 'Media code'-block currently does not work you will still get 8x write descriptors if your drive is capable of writing at this speed.
Added a 'More info'-button that will redirect to an on-line resource that contains additional information.
Slightly different, more detailed method of reporting the certified recording speeds of DVD+R/+RW discs.
The Media ID on DVD+R/+RW discs is now shown as a 3 digit ID (e.g. 03 is now shown as 003)
Various small changes, fixes and improvements.
