ISO files are images of an entire volume that are burnt to optical media. There are several apps that can examine and extract the contents (WinZip, for example) but I don't know if the contents (assuming media) can be streamed right from the iso file. You can a.) burn the images to a CD or DVD (depending on the format) and play them that way, or b.) extract the media files, assuming they are in a playable format and then use the media player.
