I get it from
http://www.kpopella.com
Has Dramas too.
Then you just gotta click to the Subbers site.
Usually in the description from that site.
For Example.

For Dream High I went with Haru2Subs.
If you don't know how to use the subs file, it's simple.
Open video in VLC.
Drag and drop the sub file onto the video.
Then I found this site.

Which is where I got the Rania Perf since kpopella didn't have it.
It also seems to have J-Idol DVDs...
