There's a Python script floating around called youtube-dl (which is an open source project), an example invocation would be something like this: youtube-dl https://www.youtube.com/watch?v=O1MIVOTstF0 depending on the video format, either MP4 or flv, the file would be saved to disk as 'O1MIVOTstF0.mp4' or 'O1MIVOTstF0.flv'. It is cross-platform friendly, and can run under any environment provided the Python run-time is installed. Then push that across using a video player on the handset to play the youtube video - that is off-line, thereby minimizing data caps limit. Addendum Am not 100% sure if Android has a video decoder for flv format... so that is an open ended question depending on what video player can support it.
