Note: The malaysian disc has an annoying AOL-like logo that appears every fifteen minutes when english subtitles are selected.
However, it also has a 26-minute making of WITH english subtitles (while the HK disc doesn't have any big extras).

The Edko disc has a bit more grain and looks slightly sharper.
Not much, though.
If you want a quality presentation: get the Edko.
If you care about extras: get both.
