DVD-R media compatibility and write quality:
In these tests we will be using a Lite-On SHW-1635S drive with firmware YS0N. Mid way through the review the SHW-1635S became unavailable; we continued the tests with a Lite-On SHW-16H5S with firmware LS0T along with K-Probe to measure the disc quality. We will also be using the NEC ND-3540A with firmware 1.03 along with CD-Speed for our read-back tests.

Low levels of PI and PIF errors on this disc, make this a very good result. Recommended!

PI levels are high near the end of the disc but are well within specification. PIF error levels are low and our read-back test is perfect; a very good result. Recommended!

| PI-8 errors Average/Sec: | 46.23 |
| PI-1 failures (PIF) Avg/Sec: | 0.27 |
The PI error levels are quite high throughout the burn and PIF levels are fairly constant throughout the burn, but all well within specification. The read-back test shows some problems and the disc was only burned at 4x. A poor result.

PI and PIF errors are out of specification and our read-back test shows many problems with this disc. A firmware update can probably fix this problem. A poor result.

| PI-8 errors Average/Sec: | 2.41 |
| PI-1 failures (PIF) Avg/Sec: | 0.06 |
PI errors are low throughout the disc as are PIF error levels. However, a cluster of PIF errors at the end of the disc causes a slowdown in our read-back test at the end of the disc. The result is ok but could be improved.

| PI-8 errors Average/Sec: | 9.74 |
| PI-1 failures (PIF) Avg/Sec: | 0.19 |
PI error levels are reasonably low and PIF errors are fairly constant but well within specification, and we have a perfect read-back curve. The result is good, but our disc was only written at 4x.
DVD-ReWritable media:
We used the same testing procedures as we did for DVD-R media.
Our obtained results can bee seen below.

| Manufacturer: | CMC Magnetics |
| Code: | CMCW02 |
| Disc Type: | DVD-RW |

PI errors are overall very low, PIF errors remain fairly constant throughout the disc but are well within specification, and we have a perfect read-back curve; the result is good.
To sum it up: Overall, the write quality is generally good on DVD-R and DVD-RW media, but some improvements are needed on some 8x and 16x DVD-R media.
