A few years ago VCD legitimate popular, we will often VCD, Mpegav directory under the file copy directly to the hard disk, so not only can reduce drive wear and tear, but also to ensure the VCD of smooth playback. Now, when we play a DVD movie when the DVD drive is more busy, if you can spend some time the DVD content on the disc is copied to hard disk for playback, that's not it can be the optical disk toil to liberate? Before the application of the VCD on the copy method can directly apply to on the DVD?

First, the direct copy method

Earlier introduction of DVD common sense when it comes to DVD disc all video files, subtitles all stored in the VIDEO_TS under the VOB file and the IFO file is used to control the VOB playback important files, the BUP files are IFO files of the backup files in the IFO cannot be read when the alternative role. So, in principle, as long as we have the VIDEO_TS an entire folder all by disc copy to the hard disk, should be able to directly play.

Copy and paste operations here don't have much to say, just a copy of the time depending on the DVD drive of the multiples and the DVD disc of volume there will be a difference.

It can obtain a valid decryption key, making it easy to copy encrypted DVD files. The Copy all the VOB extension file to decrypt the state stored in the hard disk, since in that during playback of the video is not encrypted, and therefore stored to the hard disk in the file there is no encryption information.

With DeCSS technology, no matter DVD disc is encrypted, we can copy it to the hard drive, just encrypted DVD copy of the When you need by means of the application of the DeCSS technology software.
