Again I have still to apologize for my out of brain day, when I assume, the german Bruce Lee Box would be egion B. I still don't know how I even thought of it. Not to mention, that I was so sure, I would have vowed an oath on this.
But back to topic:
I compared the german (european) BD of "Enter the Dragon" with the Hong Kong release:
Hon Gong release features the original Chinese written intro, DTS-HD Chinese Audio. A bit more screen. But:
The image quality is someway worse than the Warner BD:
Loosing details in darker scenes. Colors seem a bit odd. General a bit worse details...
It is just a nice to have because of the chinese intro sequence, but definitly no upgrade in quality to the european BD :(
The only thing is that the HK does not suffer from the fine jaggies , the european Bd suffering from.
Both BDs far away from being perfect...
..so for your own judgement: A comparison (the jaggies in europea, warner version, best shown in screen #07)
