- Writing Quality

Unofficial firmware releases change the maximum supported writing speeds for certain media that can only be written at 4X or even lower. It is interesting to see the writing quality with such discs, using hacked firmware. For reference reasons, we demonstrate the following KProbe scans, along with the PlexTools scans.

Note that all the following media was supported only at 4X by the official v2.15, while with the un-official firmware (Herrie's 1.07v2beta6) it allowed up to either 6X or 8X.

• CMC DVD+R 2.4X @ 4X

• MCC DVD+R 4X @ 8X

• MMORE DVD+R 4X @ 8X

• Promedia DVD+R 4X @ 8X

• Promedia DVD+R 8X @ 8X

As we saw earlier, MMORE DVD-R media did not perform well with the un-official firmware.

On the other hand, MMORE DVD+R media performed much better, giving low PI/PIF level values, just as CMC media did. Promedia 8X discs returned the worst results in this test.

Comparing DVD-R media writing quality and DVD+R media writing quality, we could say that the NEC ND-2510A is a far better quality writer with the +R format media. However, again quality results were better with the official firmware, but speed was lower then.
