Another good result, especially the amount of PO-8 errors is low. Highly recommended discs.

The errors increased dramatically at the end of the disc, but we did not have any problems reading the disc back. All in all there should not be any problems with these discs.

The result with these Memorex DVD-R discs manufactured by CMC Magnetics is acceptable, but notice that the quality of CMC Magnetics manufactured discs varies from brand to brand and batch to batch.

Also some highly recommended discs and you should not have any problems with these either. But notice that the quality of these discs also varies from batch to batch.

Another good result, as expected from these good and rather expensive discs.

We did try some different Princo discs and got many different results, some better and some much worse than the example shown here. Princo varies to much in quality to be among the discs that we recommend.

The overall amount of errors is ok, but the reading curve shows some slight reading problems at the end. There is other discs that is better suited for the Lite-On LDW-811S than these.

This is really low quality media and you should try to avoid it at all cost.

It seems like the Lite-On is not correctly calibrated for this media at all since most other writers is able to write this media type with acceptable quality. Stay away from these if you have a Lite-On LDW-811S.

Another media type that is rather low quality, and the only wise decision is to stay away from this media.

Now this is what we could call a bad result! The disc ends up as a complete coaster, but on the other hand; this is some of the lowest quality media available on the market.

While the result is not bad, it's far from as good as we hoped. Most other writers are able to write these discs with better quality.
Again we present a table with various media to see if all media types are supported at certified speed.

*This is a very problematic Princo disc type that few writers are able to recognize and write successful, and the Lite-On are not able to detect the disc.
Overall thoughts: Not that bad, most quality discs are written with quite good results and only a few discs are not supported at certified speed. But there is room for improvement on some disc types like Mitsubishi 8x DVD+R and Lead data 4x DVD-R for example.
This concludes our DVD-writing tests so head on to next page and read about the packet writing performance of this drive…
