Im trying to run video files from a CD so its not an ISO.
"The International Organization for Standardization (ISO) is a worldwide federation of national standards bodies from some 140 countries...", that among other things, defines standards for things like how CD roms are formatted.
So, do as the guy in that link says: Install wine, get ISOBUSTER and give it a go.
In future if you want your CDs to be readable by anything other
than vista, do not
burn them with vista. Even winxp cannot read CDs burnt on vista it seems.
