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 overspeed 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.

Philips 16X DVD+R @ 8X

Traxdata 16X DVD+R @ 8X

3A 8X DVD+R @ 8X

CMC 8X DVD+R @ 8X

Intenso 8X DVD+R @ 8X

Optodisc 8X DVD+R @ 8X

Philips 8X DVD+R @ 8X

Ricoh 8X DVD+R @ 8X

TDK 8X DVD+R @ 8X

Traxdata 8X DVD+R @ 8X

TY 8X DVD+R @ 8X

Verbatim 8X DVD+R @ 8X

BeALL 8X DVD+R @ 8X

- Summary

Writing quality is improved when recording at 8X when compared with the 16X writing quality. However, in some occasions, high PI error levels indicate average quality. BeALL 8X +R media was unreadable with the Plextor 712A and reported an unrecovered error with the LiteON drive. Apart from BeALL media, all other 8X +R media were readable. Best results came with TY and TDK media.
