DVD images follow the UDF format and there is some UDF support through libcdio. ( libcdio also supports ISO-9660 image reading, but at present there is no VLC access plugin which uses it. The kinds of Compact Disc formats supported are CDRWIN's BIN/CUE format, cdrdao's TOC format, and a limited set of Nero (NRG) formats. Some of these options may not be the default for your operating system. For CD-image support VLC has to be compiled using libcdio ( -enable-libcdio) and the various plugins which use libcdio need to be selected ( -enable-cddax, -enable-vcdx). You can simply choose Open file and pick the CD-image. If you have a CD-DA (audio CD), SVCD, or VCD packaged inside a CD-image, in some cases VLC media player can play this without you having to mount it or extract it.
