In regards to the actual documentaries, the Miami versions are merely updated and have a few corrections.

However, these 2 DVDs did not have any DVD extras (which are listed on the back covers of the originals) and no DVD_ROM folder extras either.

Since I wanted the newest version and with extras, I rebuilt the original DVDs - replacing the original documentaries with the updated Miami editions. Nothing was modified or re-encoded and are DL DVDs.

Then, since I wanted to make SL versions, which obviously entailed re-encoding, I decided to take advantage of the situation so I also deinterlaced, sharpened the image a bit, made them progressive and adjusted the chapters to match more closely to chapter points of the originals.
