Philips DVDRW885K Double Layer - Page 18

For checking exactly what the DVDRW885K reports with CDSpeed Quality Test, we used three different media, burned on other recorders. Each media was then measured with the well known AudioDev SA300 DVD CATS system at 1X.

Please note that the posted results are only valid for the specific tested DVDRW885K drive. Notice that using other 885K drives can produce totally different results.

#4th Test Disc - PISum8 Comparison - 8X Reading speed

The difference beetween CDSpeed's results and those of CATS are again different. The trend is almost the same but the values are over two times up for the Philips drive. Things are slightly better with Jitter comparison. The differences beetween the values are small, while the trend is very similar. Even when we set the reading speed for the Philips drive to 8X, the test was carried out at aproximately 2X.

#4th Test Disc - PISum8Comparison - 6X Reading speed

Once again the true reading speed with the Philips drive was 2X, instead of 6X. The same is happening here as with 8X, with both the Jitter and PI graphs.

#4th Test Disc - PISum8 Comparison - 4X Reading speed

Instead of the 4X reading speed that we set, the test was done at 1X.
