In multikit, for example, you can view an announced directory using the "Open directory from parameters" command (in the "File" menu), or, equivalently, typing <Control>-o. You will then be prompted for the directory's id, multicast address, and port. You can fill these in from the values shown in liveCaster's window.
Fortunately, the data format (MAFP) used by liveCaster is a simple, text-based format that is easy to process. For example, if you are familiar with the Tcl scripting language, you may find useful the customized multicast shells "groupsock_tclsh" and "groupsock_wish". (Live Networks (LIVE555.COM) can provide these shells upon request.)
