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

- CMC MAG 16X DVD+R @ 16X

- MKM 16X DVD+R @ 16X

- Optodisc 16X DVD+R @ 16X

- Philips 16X DVD+R @ 16X

- Ridisc 16X DVD+R @ 16X

In order for LG to improve things with Ricoh 16X DVD+R media, the supported speed has been reduced from 16X to 8X in fw DL11. For this reason, we did not repeat a burning but simply present the following scan, with fw DL10 used in the burn.

- Summary

Taiyo Yuden and Mitsubishi Chemicals produced excellent writing quality.
