The only thing I've ever actually used on XBMC is Navi-X. I used it to watch the first half of the ND game on the live TV thing last night before I turned it off in disgust...thought about turning it off after the first quarter. I've been having more and more trouble with it lately, but still get it to work most of the time. I have favorites stored, though, so I don't have to use the search function much because that seems to be where most of the trouble lies. It might be a compatibility issue with the versions of XBMC and Navi-X that you have, too. It seems to work better on the TV hooked up to my desktop than it does to the one I use in the living room that's hooked up to my laptop.
