Hong Kong versions of CD+DVDs?

[Xianghua]

Ok I have a question for anyone whose bought a hong kong version of any CD+DVD on yesasia.com.

I'm aware of the NTSC and PAL formats for television, on yesasia.com it says the hong kong version is in NTSC format but doesn't Hong Kong use the PAL system? Is it really NTSC format? I want to make sure the DVD will play fine for me before I buy it. (I'm living in the US so I have NTSC)

thanks for help please.
