what more things can you do with a rgh

I recently purchased a rgh slim from Ebay already had fsd 3 installed glitches sometimes under 5 seconds sometimes under 30 sometimes even doesn't glitch on first go but glitches second go anyway is there any programs like xbmc and also doesn't xell boot with hdmi because when I push eject xbox doesn't glitch or do I have to wait long it is a corona board also have the jq360 or what ever it's called I see people but for some reason I can't log on for some reason

Also the fsd is loading with a USB with other programs in there can't I just load it of the xbox360 hardrive or can't corona boards do it thanks
