Hello, I just arrived in Singapore today, and will be here for 4 days...
I bought over 30 dvd's from Indonesia... the cheapy ones you get at the "shops" hehee.... and didnt have any trouble on bringing them in. Just put them in my suitcase and continued on my way.. no questions were asked, and didnt have to "declare" them anywhere on arrival card etc...
So I think people will be pretty safe and dont need to worry....
