Google2SRT allows you to convert subtitles from
Google Video and YouTube to the SubRip (.srt)
format, which is recognized by most video players.
You can download XML subtitles or simply type the
video's URL, and Google2SRT will do the rest.
ConsoleTube is a YouTube client for console lovers/flash haters. It takes a search term and uses lynx, sed, and grep hackery to automatically play the search results through VLC. Custom playlists are supported.
