In order to test the writing quality and readability of the burned media we used two readers 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 be taken not as the absolute criteria of the burning quality, but as an indication level.

16X DVD-R Writing Speed

- MKM 16X DVD-R @ 16X

- Maxell 16X DVD-R @ 16X

- Summary

Writing quality with DVD-R 16X media is actually very good, according to the Plextools graphs where the PI levels are below 60 while some PO were reported. CD-Speed though does not fully confirm the outcome reported by the Plextools utility, having some distorted graphs with many drops in speed. Additional 16x recording tests will be performed as soon as the next firmware version will be released.
