I wish! No, you need quite a bit of time and effort and luck to get the NG clips. Time because you've to dig through a few websites and forums, effort because you've to figure out how to download when the links are not spelled out, and luck because the links go dead really really fast.
To save you some trouble, I'll share with you the results of my research. See if you can get the clips from these places:

heaven-sj.wo.to [STH fansite]
www.sangwooforever.com [Go to "Databox" tab]
www.prettyjiwoo.net [if you read Chinese, sign up for the forum and click into the STH pages; also, click on the "VOD" tab at the homepage]
www.cjwfc.com [Chinese site also, click on "Media"]
soompi.com/forums/index.php?showtopic=133402 [Mega, mega forum for STH, should be nearly 300 pages by now]

You can also try combing through the earlier pages of this forum for period Nov 03 onwards.

Dear Jaclyn,
There are many NG of heavens i extracted from the korean dvd and put into the "vod" section of jiwoolove.com.-Chinese . Go and take a look.
