Sony Dw-D56A PDS7 Firmware update

I just got this update from Dell and now my burning speeds using DVD Decrypter are slower. Before the update I set Decrypter to burn at 4x and after the update, even though it is set at 4x, it only burnst at 2.5x. Any ideas what is going on here? Thanks.

different type of disk? if its the same one they might have revised down the burning speed for that medium. try a different type of disk

Please post the media code. You may also want to use KProbe 2.4.2 to test the drive’s burst rate (should be above 20 MB/s).
