Just my two cents on the Japanese Blus of DM and SITES.
The image quality on both movies is excellent. They do however have the credits in English rather than Chinese. It also looks to me like the titles were digitally recreated, and are not actually on the print itself. DM's Cantonese track is more complete than on previous Sony releases, but it's still not 100% complete. All the dialog has been restored, but there are a few moments during fight scenes where it switches to the English dub (grunts, screams, etc.) The music in the opening scene is also timed incorrectly. The sound quality is decent, but I feel like it could be better. The sound quality on DM in particular varies greatly. Does any Laserdisc release of DM contain the full Cantonese audio? Of course, there are no English subtitles. The subtitles from the old Sony DVD sync up nicely, but they are dubtitles, unfortunately.
