Luckily I bought 2nd hand台版 from a kind CHing 2 months ago.
台版赤壁: Video is 16:9 which is much more impressive compared with 港版 (can see more scenery)
It's not 台版將畫面放大 BUT it removes top and bottom in 港版 to make it 1:2.35
The sound quality is good (Both Dolby TrueHD & DTS-HD are available in 台版)
Frankly speaking, it's no regret to keep waiting for long time to get 台版.
