First of all you need to get a software to play the movies. You can choose between Core player, Smartmovie and DivX player. I use DivX. It is free and good. Download it from link below
labs.divx.com/system/files/private/DivXPlayer_S60_3rd.sisx
For downloading movies the best site is moviesmobile.net. It has all the latest movies.
Note: Download DivX player in Mass Memory. After installation create a folder named
' DivXPlayer ' in mass memory. Move all the movies you download into this folder. DivX Player is only able to read and play the files which are in this folder
