JIsoX has one job, but it does it well: convert a VIDEO_TS to ISO image. While Toast 11 doesn't perform the job as well as it might, but JIsoX does everything quickly and faultlessly.
You may have to juggle around your file system to locate the file you want to convert, but after a little while, this application will manage the task nicely - and for free. True, the interface is a little utilitarian, but it's unlikely you'll be using it every day. Nice job!
