Just verified, YES cycling VC off then back on fixed it.. I feel foolish for not trying that. I am using the XBMC tab in options and everything is working as advertised again. My carputer setup is a 8" xenarc touchscreen with a Acer Aspire Revo nettop Atom 330 with a dc to dc psu from mp3car.com store. I definitely will put videos up when my project is done, probably before that when I get more voice commands set up. Right now it is using the Ride Runner front-end to handle music, vid, gps (here's a vid of some guy demoing it)

I plan on dicing up a used logitech branded usb mic that came with the PS2 game socom and mounting it near my sunvisor. I noticed it was very sensitive and using it for VC testing it works well. I whipped up a quick autohotkey script to mute the master volume by half and unmute the microphone while a joypad button was held down. So as long as I keep the windows up on the freeway it should work fine.
I like that idea of a repository of user generated groups/presets, I think it would be popular
