Hehe. That's okay; don't worry about it. This used to be the "LiteOn forum" until it was recently renamed to the LiteOn/Sony forum (because a lot, though not all, of Sony's drives are made by LiteOn)... I don't entirely agree with the decision to add Sony to the forum name precisely because of confusion that it would cause for people with non-LiteOn Sony drives, but I'm not the powers to be... But because this is really the LiteOn (and LiteOn-manufacturered Sony stuff) forum, I'll most this to the general forum...
And yea, all that I can really suggest right now is to update the firmware, as chok0 suggested, or to use older 4x media.
First, do not directly link to TDB's files. They don't like that, and the link you posted produced an unauthorized referrer error. Second, stock firmwares are preferred unless the user prefers an unofficial one because unofficial ones will void the warranty. Finally, the latest is 2.0e, not 2.0d, as indicated in your first post. I edited your link to point to the rpc1.org firmware database instead.
Hmm. Post #5000 spent on an administrative post... oh well.
