I've been trying to figure out the offset for EAC for my Sony DVD DDU1621 drive. None of the disks which EAC said were in its database worked for me - I guess I had a different pressed version. I found this site which says "Offset 2256 bytes (564 samples)" about halfway down the page. However, this post claims a 594 offset for this drive. I couldn't find the drive on any other lists of offsets. Is there a way I can verity which it is?

Using +594 gave me a result that matched another report for another drive. It must be the good offset.
The other site must have measured the combined offset of their burner and the Sony drive.

All the settings you need for Sony DDU-1621 on EAC:
