Covers (SVG wrapped) just work for so many users, that you must be fighting Calibre to get it a little more 'your way'.
Maintaining Aspect is 900% more important to me, than filling every inch of the screen.

I bought Laser Discs in the 80's because I could see movies in widescreen. So what, if there were black bars top and bottom.
Well, Calibre creates the code that I like the best (I didn't just come up with that code...I got it from the HTML in the titlepage.xhtml file after adding images and converting), so I'm still wondering why the conversion process isn't consistent and creates a different set of code when just converting vs. the code it creates when adding an image and converting. I'm not fighting anything; just trying to find out why Calibre uses two (or more) different cover codes and why one of them doesn't center the image. I guess I'm looking for a setting that will let me choose which HTML code I prefer for the cover image, instead of getting whatever HTML code Calibre decides to use when I convert (which I realize is probably dependent on the existing code in the file before the conversion).

I'm not trying to fill every inch of the screen. That's why I like the code I posted the best--there is white space on both sides, the aspect is maintained, and it's perfectly centered with no white space at the top or bottom. I also prefer to maintain the aspect, but I also would like the image centered and Calibre does not always center it.

And what you said in your first paragraph is what I meant. I was just saying that I finally realized why sometimes Calibre Convert creates a duplicate image. I've never taken the time to experiment very much with some of the conversion options until recently, because I was spending most of my time learning CSS, how to format an ebook, learning all the editor functions, and editing scanned ebooks (or just adding cover images) before I progressed into my current stage of working with ebooks.
