I do roughly the same. Home movies are tv shows, I have each year as a season (2007, 2006, 2005, ...) which is nice now that apple tv gives the divider bar, and I put the month number as the episode number (1=jan...). This sorts by year then by month without having to play around with the movie name, it doesn't sort within month but I really don't need that level of granularity.
