OVERALL: R1

All of the "X-Men 1.5 X-TREME" releases (apart from the R2 Scandinavia) have DTS 5.1 audio tracks, but the R1 has the "Marketing the X-Men" section and much better packaging.

The R2 Scandinavia "X-Men 1.5 X-TREME" release should be avoided, since it duplicates certain extras on disc one and two, due to re-issuing the older 1-disc release as disc one.
Sweden got a separate release from the rest of Scandinavia.

Do note R6 has a full bitrate DTS soundtrack.
