Sony ddu1621 specs question

I’m new to this, and apologize in advnce for probably putting this in the wrong spot to begin with.

Before even getting into this, first things first. the drive plays dvd movies (without sound cuase duh, i forgot i actually need a player to hear that) and even verified it reads cdr and cdrw. The ide cables are correctly placed, and slave/master is set properly with the cdr/w burner i have. so as near as i can tell, i have all of that right.

here’s the problem, from everything i’ve found, the ddu1621 is suppossed to support dvd+r (as seen on http://www.techtree.com/techtree/jsp/article.jsp?article_id=50521&cat_id=631). I copied a game onto a dvd+r and guess what, the drive wont read it (doesn;t even recognize there is a disk in there). so long story short, i checked mine with nero info tools, and it does not show the drive supporting read features for dvd+r. so here’s the question…

is this software or hardware? i tried to download the latest firmware from sony, but when i try to run it, it tells me that it’s an incorrect firmware version (which could be either hardware or software). I’ve included my nero scan info below, but would love to know if there is anything i can do to get this thing to run burned dvd+r disks or should i just be buying a new one (and remember, i got two kids so they need to eat first). any and all help is appreciated.
