|Spring, Summer, Autumn, Winter... and Spring||R4|
The R1 version of Spring, Summer, Autumn, Winter... and Spring has only a couple of differences to the R4.
The R1 version differs from the R4 version in that it features a Korean Dolby Digital 5.1 audio track and has French subtitles as well as English, although the R1 version is missing the trailer and image gallery.
The Dolby Digital 5.1 audio track might be a nice touch, but I imagine it would be filled with mainly ambient sounds and music. The Korean Dolby Digital 2.0 audio track on the R4 is of excellent quality and very much suits the film. I believe the Dolby Digital 5.1 audio track may be wasted due to the large number of quiet moments in the film.
If the French subtitles aren't an issue, I would sacrifice the Dolby Digital 5.1 audio mix for the Dolby Digital 2.0 audio, coupled with the superior PAL transfer on the R4 version.
