Thks for the clarification

If the NME is OK...
We covered the verification of the burn; burner; media; compatibility to Hitachi, chip...
It seems the only thing left is the image itself. Now you need to find if it isthe Xtreme part of the image, or the NME patch made on your image by Associator that is the problem. That was the reason of my suggestion.
Last two things I can see
Some members reported that Associat0r sometimes as a prob to extract the ss and move it to the proper location using the Convert tab. Some people made it work by extracting the ss.bin from their image (use ssmerge, schtrom, XBCr) and then they called associator to do the merge+conversion using the seperate files in the Merge tab. For some it seems to do a better job at inserting a ss at the right place then moving it.
1) so do your image in XBCr on your SHD162C, then go in drivetools tab and this time extract the ss only.
then go in imagetool tab and do a stealth check to be sure all piece are there.
2) go in associator and select Merge tab select the .iso and the ss.bin you just extracted.
Since you have a SH-d162c and XBCr, It is likely the image is OK, so it seems a lot more an NME patching issue. There is a forum specialized on
Chip (including the NME) would could also help you.
