Perhaps, although I develop for STB:s at work, and I know how amazingly price-pressed the hardware is. Seriously, it's designed to show live HD, but the developers manual for one manufacturer, there's a performance-warning about animated GIF:s (not kidding). My guess is, the only FFT the box can manage is the one hard-coded in the video-chip, which can't easily be exploited for other means. Of course, I don't know what HW the Tivo is using, perhaps they're just lazy. :)
