大陸的DVD跟香港的DVD格式相同嗎?

大陸DVD跟香港DVD格式是一樣的.
事實上每部DVD機的讀碟能力是有分別的,遇着質素較差的大陸DVD有時會出現不能讀碟的問題,我也還過即使香港正版DVD機也會有一些機讀到,有一些機讀不到的問題.
曾經有人說過貴機讀碟能力反而不及平機高,因為鐳射光束調得太強會縮短鐳射頭壽命的.

香港好難搵到唔係全區碼既DVD機,除咗PS3.翻版天堂大陸都好難搵到唔係冇區碼既DVD碟,我咁耐都未見過真正6區DVD,大陸係6區唔係9區,DVD9只代表單面雙層,唔關區碼事.

All DVD format is the same. The reason for not being able to read in some DVD players or computers is that DVD discs are encoded with regional protection. DVD discs of divided into different regional codes. The codes of Hong Kong and China are different (3 for Hong Kong and 9 for China) and so if your DVD player is not ALL CODE capable, it may not be able to read DVD discs of other regions.
