Picture- Widescreen anamorphic - 1.85:1. Columbia's picture quality is a notch above the Bitwin, which was too bright and had considerable grain. Columbia's transfer has far deeper contrast, better blacks, and less grain, thus improving the sharpness and color overall. While there is still the occasional softness, dirt spot, or minor light bleed, for an Asian import the image is pleasing, especially when compared to the previous releases.

Sound- Dolby Digital 5.1 Original Korean, as well as 5.1 French and English dubs, with optional English, French, Portuguese, and Spanish subtitles. Once again a very nice, dynamic soundtrack, action and dialogue coming through strong with okay 'ka-pow' 'BOOM' surround. The only difference between Columbia and Bitwin in terms of sound, are Bitwins additional DTS and Dolby Stereo options.

Extras- Considerably less than the 2-Disc Bitwin, however Colombia offers extras that are English friendly, something sadly lacking in the Bitwin.--- 28 Chapters--- Trailers for Shiri, Crimson Rivers and Tailor of Panama--- Music Video "When I Dream"--- And by far, the most welcome extra, the one hour "Making of Shiri" documentary, now with English subtitles. Basically this behind the scenes doc covers all aspects of the production, financing, acting, stunts, post production, filming- it is packed with nice little bits for everything you may be curious about. It is nicely packaged with every moment of the production being filmed- actors training, having paintball wars to get used to shooting, the large chunk of the budget going to gun props from Hollywood, actors hurt during filming, and a great intimate moments where one female actress shows her deeply emotional acting during a key scene.

Conclusion: So, I'm not going to say owners of the Bitwin should dump it for the Columbia. Each version has its own benefits and setbacks. As a consumer, you can decide if you want better picture and fewer extras?, lots of extras that aren't English friendly?, or if you have to have a DTS track and not just a good 5.1?, and how much you would like to spend/wider availabitly? For people that dont own it at all I personally would steer them towards the Columbia= lower price + better transfer + English friendly .
