|Paranoia Agent-Volume 1: Enter Lil' Slugger||R1|
The Region 1 and Region 2 UK discs are identical in content, aside from trailer differences. I would presume the Region 1 disc contains a native NTSC transfer rather than a conversion.
The Region 2 Japanese releases contain only two episodes per volume, but have Linear PCM audio.
I'm going to give this to the Region 1, simply for the fact that I loathe NTSC -> PAL conversions.
