I just saw the MKV and compared it to the AVCHD file that I muxed from the MKV to burn ont a Blu-ray disc and there is definitely a noticeable change in quality so hopefully when the finalized Blu-ray is released that issue will be fixed. I don't really know much about burning Blu-rays other than following exact directions so it would be very helpful if Harmy were to release a step by step guide and maybe I really did not need to convert out of MKV before burning to Blu-ray? My reference scene for the comparison was the lightsaber duel between Obi-wan and Vader
