DVD Recording Tests

- Writing Performance

Optorite DD0203 supports DVD-R/RW and DVD+R/RW writing. The maximum supported speeds are the 4X for DVD-R/+R, 2X for DVD-RW and 2.4X for DVD+RW.

We burned 4315MB of data on Verbatim 4x DVD±R, 2.4x DVD+RW and 2x DVD-RW media. The recording times are illustrated in the following table. For comparison, we also include the writing times of Sony DRX-500UL:

The following pictures come from Nero, after successful burnings with Optorite DD0203. The amount of data is the same for all the tests.

• 4x DVD-R

• 4x DVD+R

• 2.4x DVD+RW

• 2x DVD-RW

Optorite DD0203 selects the maximum allowed recording speed according to the inserted blank DVD discs. The drive was fast with all the 4x DVD recordable media we testes. In the following table you can see the maximum permitted writing speeds with various media.

*IMPORTANT UPDATE

After some more testing and the contribution of our readers, we discovered that the some DVD-R media recorded in DAO mode are not fully compatible with some DVD-ROM players. The problem was introduced in the firmware v2.07 and is still not solved with latest firmware releases.

Newer DVD-ROM players should not have problems with playback. For example, Liteon LTD-166 can read the media fine, but not their older model LTD-163. The same is applied for Pioneer drives. The 6th generation DVD-ROM drives (DVD-116) works, but not the 5th and earlier generations. According to Optorite, the problem will be fixed in the upcoming firmware release.
