(Firefox + DownloadHelper Extention + VLC Media Player) = Flashdrive storing and playing videos from YouTube/Google Video.
Problem was, online videos are typically converted into flash files, and windows media player or quicktime won't play them. VLC will play nearly everything. The DownloadHelper extension searches the web code for file types and lists what can be downloaded.
Bummer is, my 256mb flash drive is losing space fast.
