Well, people still buys pirated cd/dvd are due to several reasons.

One, the pirated versions are way cheaper than originals (no royalty). So, people can purchase the game/album/movie/songs that they want. Besides, they can get more titles from the amount spend (eg: RM200 for 20+ pirated titles and 3~5 originals). Due to low cost, some people won't feel disheartened if they throw away pirated cd/dvd after using them.

Second, it is easier to get the cd/dvd you want in pirated version (originals are either late or not available in M'sia), Though the quality for the pirated versions depends on luck & subjective. Sometimes the original DVD movies/songs are censored [too much] / banned. This may drive people to sought for pirated cd/dvds.

Just my 2 cents.
