Abstract: A DVD play system, a display apparatus and a DVD display method are provided to transmit skip information to a DVD player to move a track until a screen appears when error exists in a DVD. A DVD play system comprises a DVD player and a display device. The DVD player performs focusing and tracking to read a recording signal from an inserted DVD disc. The DVD player comprises a DVD data processor(201) which processes and outputs digitized DVD data of an RF form. The display device is connected to the DVD player to play and display the output DVD data. The display device comprises an IR light receiving unit(101), a controller(102), a memory(103) and a play determining unit(104). The display device includes an error information detection unit(105), an MPEG decoder(106), an OSD unit(107), an image processor(108) and a display unit(109). When error of the DVD data occurs, the display device automatically skips the track with the error to the DVD player based on the error information list of the inserted DVD disc. The display device transmits a message related to the error through an OSD setting command by using a consumer electronic control protocol. The error information list of the DVD disc comprises at least one of a title of a DVD, playtime of the DVD, and track time or jump time in which error is generated.
