Sometimes R2 releases come out before the R1 releases. Farscape is a case in point. The number of US Scapers I've heard moaning because they hadn't thought ahead enough to buy Multi Region DVD players "cos R1 is better".
I got my DVD player back in the days when it cost £20 extra to get an MR player. it has 10 Region Settings:
0 : Plays from any region and region free DVDs (Some newer DVDs won't work on this setting as they are more specifically coded)
1-8 : Exactly emulating Region 1 thru 8 avoiding the problem mentioned above.
9 : As per 0.
A bit more low tech than the more modern MR players but gets round all region specific coding tricks as it can become a single region player for any region.
Hi-tech ain't necessarily better. And better is the enemy of good enough!
