I have used kmttg to extract the meta data .txt file and have experimented with it and using the push feature of PyTivo. What have worked is the title, seriesTitle, episodeTitle (or at least some of it, without looking at the .txt file), I managed to create a folder for a series and each episode titled the way I liked, onto the TiVo. Although I don't see the .txt but it affected the way videos sent to the Tivo playlist.
