There is also another possibility --- if the content is copyrighted, the owners may opt to introduce deliberate errors in order to prevent copying the contents of the disc. If that is the case, vlc will attempt to read only the files it needs, and would not see the error, while cp would try to copy everything, and get stuck. > Is there some way or tool that will make a copy of the dvd > using (or at last preserving in the copy so that vlc can use) > the error correction stuff on the dvd so that the copy is > playable even when there are some errors? Others have suggested dd and variants, to make an identical copy of the data on the disc. However, if your aim is to get a copy of the video content of the disc, you can also use mplayer to copy the video to your HD. Something like this: mplayer dvd:// -dumpstream -dumpfile my/video/file.avi This will "dump" the actual movie into a file, rather than onto the screen (and speakers). You can be more selective by using dvd://2,4-6 to play only the tracks you are interested in, or use -dumpvideo or -dumpaudio instead of -dumpstream to separately copy video only or audio only. You may want to get familiar with "man mplayer". Just don't get too scared by the amount of options in the manual. :-) The quality of the dump is of course equal to the original, since it's just copying, not transcoding. The resulting file size will be the size of the video data on the dvd disc itself (most, but not equal to the size of the dvd disc). The dumped file can be played by any video player (vlc, mplayer, ...) that supports MPEG, by pointing it to the file. In general, as far as mplayer usage goes --- if you can see the video on the screen by playing it in mplayer, then you can also dump it in a file instead, to make a copy. And generically mplayer will play everything you throw at it, including copyrighted dvds with deliberate errors etc... ;-) Oh, and you may also want to install the libdvdcss package from the old Livna repository (http://rpm.livna.org/), in order to get around the CSS enryption (Content Scramble System) for some copyrighted dvds...
