Yeah, by DVD-9 I mean Dual Layer Single Sided DVD. More here.
When you buy / rent DVD-9 movies, this is exactly what you get: a
Dual Layer Single Sided DVD. In China / Indonesia / etc they sell
these movies around 2-3S$.
Now, if you go and buy the blank DVD-9 media from a Singapore
store, they'll sell it for about 10S$!!
I am missing something here...
