Try burning your Back ups on Verbatim dvd-r instead of those philips DVD'Rs. My TDK's are no longer recognized because they are cheap CMC Magnetics Media. The older 1.2 firmware might support those Philips Dvd+rs, and the new firmware which has been updated to read silvers, etc. may not like your back ups. Only use good media to back up your games. Either use Taiyo Yudens , Verbatim, or Sony DVD's. Anything else is cheaper media, that will give you problems.
the person who installed it did it the other way(the alternative one) here is the pic

The first link you showed is for the Infectus 2, I believe because the Argon doesn't use 5V but 3.3V . The diagram you should be using for the Argon is
