Way to watch MP4 files on my Tivo?

What's the best way to watch a home movie MP4 file on my Tivo Roamio? Is there an app that works best for streaming it there, or another way to transfer it to the Tivo?

Sorry, the last time I tried this was when Tivo had their Windows app and I just transferred using that to my Series 2...
