Streambaby requires a Tivo HD/S3 unit. It uses the same underlying mechanics as Youtube support which Series 2 units do not have. As for your pyTivo woes, you should post in the pyTivo thread or over at the pyTivo Forum (http://pytivo.sourceforge.net/forum/). Some versions of ffmpeg have trouble with certain avi files even though they might play on the PC fine. ffmpeg isn't as forgiving for slightly out of spec files.
