BenQ DW1620A DL Recorder - Page 25

DW1620A DL vs. SA300 - Page 4

The BenQ DW1620A can report PI and Jitter values from burned DVD recordable/re-writable media. What's rather disappointing is that the drive cannot read the media at high speeds, since even at 8X reading speed, the real speed is around 0.5~1.3X. The scanning interval also is not 1ECC but 8ECC, dropping the accuracy of the drive, since the sample count is low.

Please note that the posted results are only valid for the specific tested BenQ DW1620A DL drive. Using other DW1620A DL drives can produce totally different results. Be aware!

#4nd Test Disc - PISum8/PIF Comparison - 8X Reading speed

The PIF error rates are low enough just as in the CATS scan, even though the values are not at the same levels. The reported Jitter tends to increased in Layer 1, which is also reported with the CATS scan. The reading speed is low, 0.9~1.5X, so it will take much time to scan a disc, not reccomended for most users...
