4-3 Selecting the desired DVD menu Item Some DVDs have title menus and chapter menus. Press MENU or TITLE,the screen shows the menu.Then use direction buttons to select the desired item,press PLAY. 4-4 Selecting the desired MP3 folder Use arrow button to select the folder you want to play. Then by pressing the PLAY button ,you can see the the file lists under the folder.
4-8 Slow Viewing When you want to view the disc contents very slowly in forward or reverse direction, you can do that by pressing the SLOW button. When playing DVD,there are six choices:SF2X, SF4X, SF8X, SR2X, SR4X, SR8X. While playing SUPER-VCD OR VCD,there are three choices: SF1x, SF2x, SF3x.Take DVD for example, to view at slow 2x in reverse direction ,press the slow buttom four times. To resume playing normally ,just press PLAY.
