Well we are trying every aspect.

I honestly feel it's going to turn out to be the usual reason of a slightly differently aligned laser in your current PC hardware. Everything seems to be pointing at that.
Were all the others burned on the same burner? It may be that one that was a little "off" if they were. If they were burned on different burners, it's the current one.
As a final thought, do the CDs play on non-computer players? (CD/Mp3 compatible players, DVD players etc)? If they do, that would pretty well rule out bad media.
Home burned CDs and commercial CDs differ remember - home burned cause far more problems.
