Podcast Favourites after Factory Restore?

Hi there,
Luckily I haven’t had to Factory Restore my AppleTV since I first started using 2.1 (coming from a hacked 1.1) and then started using ATVFlash @ v3.2.

Now I think I need to do a Factory Restore, weird stuff happening.

But what will happen to my Podcast Favourites? I have dozens of these and would obviously like to avoid having to search for them all again.

Does a Factory Restore delete them? If so is there a way to back them up? A file located somewhere in Media that i can copy back after the FR?

thanks, Anthony.
