How to play a file with the extension Ifo

According to the CD (DVD-VIDEO) standard, a standard video_ts folder should contain three types of files: vob, IFO, bup, next, let's take a look at their respective functions. Vob (Video Objects video target file): The vob file is used to store video data streams, audio data streams, multi-language subtitle data streams, and screen data for menus and buttons in a DVD Video. A vob file can store a maximum of one video data stream, nine audio data streams, and 32 subtitle data streams, therefore, a DVD film can have sound in up to 9 languages and subtitles in 32 languages. Ifo (information file): The Ifo file is used to control the playback of vob files. The file contains the control information about how and when to play the data in the vob file, such as the start time of the section, the location of the audio data stream, and the location of the subtitle data stream. Only by reading Ifo files can the DVD host or playback software organically combine various data that constitute a DVD Video for playback. Bup (backup file): The Bup file and Ifo file have the same content, which is a backup of the IFO file. Because the IFO file is very important to ensure normal video playback, you need to keep a copy so that you can still get the relevant information by reading the Bup file when an error occurs in the read of the IFO file. Through the above introduction, we can see that as long as the playing Software reads the IFO file, it can achieve the purpose of controlling all functions in the DVD film. So how to implement it? In fact, it is very simple. Our widely used DVD player software powerdvd XP 4.0 itself already provides this function: after powerdvd XP 4.0 is started, press Ctrl-O or click "select Source File" on the playback control panel, and then click the "open DVD file on hard disk" menu item, in the pop-up dialog box, select *. ifo file, you can use language selection, subtitle selection, and other control functions like the DVD in the playing disc. It is no different from playing directly in the DVD drive.
