- Writing Quality

In order to test the writing quality and readability of the burned media we used two readers equipped with two software applications:

- The LiteON SOHD-167T with patched firmware being able to read DVD5 up to 16X CAV and DVD9 up to 10X CAV. For the transfer rate tests we used the latest Nero CDSpeed version.

- The Plextor PX-716A with the latest available firmware. For scanning the disc, we used the latest PlexTools version at 2X CLV reading speed, BURST mode, with middle accuracy.

In general, a "perfect" disc should have a smooth reading curve, very low PIE/POE and zero (0) POF error rates. Most times however, even though a disc has very low PIE/POE error rates, the reading curve may not be smooth containing dropoffs. Due to the fact that we oversped the reading capabilities of the LiteON SOHD-167T, such drops are expected, especially near the outer area of the disc.

The measurements below should not be taken as the absolute criterion of the burning quality, but as an indication level.

- Verbatim DVD+R DL 8X @ 8X

Unfortunately, both the Plextools and CDSpeed utilities could not successfully read this DL media, due to the bad writing quality.

- MKM DVD-R DL 4X @ 6X

Bad quality media reported this time as well, with the CDSpeed utility failing to read to the end of the tested media, and Plextools reporting high values.

- Traxdata DVD+R DL 2.4X @ 4X

- Traxdata DVD-R DL 4X @ 4X

Overall poor writing quality for DL media, with most of the discs rendered unreadable. We hope for a future firmware release to fix the problem with these DL media.
