A method for editing a video data stream is suited for converting an analog AV signal into a MPEG file in a recordable player. The method includes the steps of: converting the analog AV signal into a plurality of continuous digital frames; inserting time information onto the digital frames; and encoding the digital frames with the time information into the MPEG file and recording the MPEG file onto an optical disc. In this way, when the recorded disc is played by different optical disk players, the time information is always shown on a screen at the same position.
