Thanks for this advice guys-
With your help I was able to rotate the dmd (from the script- changing the value in the regestery didn't work as it kept getting changed back to a 0, I'm assuming the script was resetting it with the line that was already there, setting of 0)
I also didn't know about the right clicking of the dmd to show boarder/drag tab. Makes it easy to resize and drag around, even to 2nd or 3rd monitor ( I am using 2, but will use 3 when I build a cabinet).
I did notice when I removed the boarder that the dmd window resized itself back to it's smaller size though. I'm not really sure how to do it correctly, but after re-sizing and positioning the dmd, I left the boarder on the dmd, then exited the table and it seemed to save it, as it was (almost) where I had put it before exiting.
My backglass has a static dmd image, which I overlayed the working dmd onto using the teqinique above. But I cant get it to match up exactly. The dmd is in a nice position, but the backglass seems stretched a bit too much. Now if I can figure out how to resive the backglass image a little smaller, I think I will be in business
