From pyTivo - Wiki
Python Version 2.5 or Greater
pyTivo requires Python 2.5, 2.6 or 2.7. If a binary package (i.e. .rpm or .deb) isn't available for your distribution, grab the source from http://www.python.org/download/. "./configure && make && make install" is likely all it will take.
pyTivo requires FFmpeg. If a binary package isn't available for your Linux distribution (doubtful) or you just want to build it yourself the source is available from http://www.ffmpeg.org/download.html
