well some stuff works like the guy above this post said ( he pretty much sumed it up )... although the main thing i use QUIX for is making ISO's from the xbox into the pc which this dont work unless your using avalaunch as your dashboard.
but i think as far as transferring ISO's from the pc to the xbox i think it will work with most other dashboards in that case.
although generally speaking i think overall if you want to be safe it's best to use QUIX with avalaunch... although i aint used avalaunch as my main dashboard in a while i keep it for that occasional rare use
p.s. i just use XBMC with MC360 v1.02 as my main dashboard (i used to use UnleashX with the "adsorption" skin until mc360 came out)
