The primary difference between the Mei Ah version and the Mega Star (same as the US Tai Seng) version of Royal Tramp 2 is that the Mei Ah DVD features a 4:3 (full screen) aspect ratio. The Mega Star version is Letterboxed (widescreen) and has a few more extras such as a trailer. Also, the listed running time of the Mega Star version is three minutes longer which suggests additional footage may be present. The Tai Seng version is just the Mega Star version with a Tai Seng sticker on it.
