From what I have learned with the Xbox one that Avchd files burned to duel layer discs do not work with the Xbox one you will need a blu ray burner just download ConvertXtoHD and stick the iso file and go into settings and turn letter box to stretch hit convert it will take a while then it will finish then buy some blank blu ray discs and open up imgburn hit burn files to disc go into documents folders and it will be titled what the avchd file was called then hit burn it will take about 30 minutes and stick it into your Xbox one and boom the original version of Star Wars in HD
Update November 2017 now they do work Xbox one just got a update so use imgburn and hit burn disc img to disc
