The Region 4 version of this disc misses out on;
I could not confirm if our disc has been encoded for Dolby Digital 5.1 EX playback or not.
- Bicentennial Man Trailer, which is played before the main menu appears.
- Higher bit rate 448kb/s Dolby Digital 5.1 soundtrack.
- Additional Spanish language track
- DVD-ROM Extras
The Region 1 version of this disc misses out on; There isn't any compelling reason to purchase one disc over the other, so it will come down to your own personal preference. For me, the R4 disc is an easy choice, as I cannot stand the reduced picture resolution and the 3:2 pull-down artefacts associated with the NTSC format.
