is your library super big? do you have lots of other apps loaded on the Fire TV?
using StickMount, couldnt someone use a thumb drive connected to the Fire TV to store the cache data for xbmc?

I have maybe 3tb of videos. The only other apps are the ones that came pre loaded. I only have about 10 apps installed on xbmc right now as well. Would this stick mount work? I take it this would need to be side loaded like xbmpdc?

The amount of space that your files are taking up on your drive isn't really relevant, the number of files is because that is going to determine the size of your library data.

On mine with about 1500 videos it the "data" size for XBMC is about 1.70GB.

But yes, you will need to first root the AFTV, then sideload stickmount. Instructions can be found here: http://www.firetvnews.com/how-to-play-me...n-fire-tv/

There's always a danger in rooting a device though, isn't there? Plus, if you root, how can you get any updates to the device? You're pretty much stuck with the last update for the aftv, aren't you?
