So what? Crap Drive? I have had absolutely no problems with 6.6.1.4, and I am most happy about the burning quality of my Plextor PX755A. I do not think it is a crap drive as you say.
I do not run other applications when I burned my DVD, therefore the fact that it takes more RAM than previously does not matter to me at all. I do not have any problems when my previous PC only has 512MB, and now I have 1GB RAM it is of no concern to me.
You are entitled to whatever opinion you may have. I just don't agree with your assertion that my Plextor drive is crap, that's all.
