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+712A 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.

Writing Quality for DVD+R burned at 16X

• Verbatim( MKM) 16X DVD+R @ 16X

• Philips 16X DVD+R @ 16X

• CMC Magnetics 16X DVD+R @ 16X

• Ridisc 16X DVD+R @ 16X

• Optodisc 16X DVD+R @ 16X

Cannot access disc

• Ricoh 16X DVD+R @ 16X

• Maxell 16X DVD+R @ 16X

- Summary

The writing quality for 16X recording with the DVD+R media we tried, was not as good as it should be. Although once again the error levels are within limits, or even lower, in CDSpeed the reading graphs reported many speed falls and difficulties while reading the discs.
