ok im still trying to burn the Despecialized Editions to BD-R but now im really getting frustrated!! I could really use some help…PLEASE!

so ive downloaded all the Harmy MKV files for each film ? what is my very next step?

i thought my next step was to open these files in TsMuxer? …https://www.dropbox.com/s/6ceu5dunbqvuzr0/de sw.jpg?dl=0

so i guess my question is, if its not these files then what files should i be opening in TS Muxer?
any help is greatly appreciated!

regards, joey

Fyi: ive also already downloaded TSMuxer and IMGburn
