Setting Up XBMC to work with HD Homerun

Hi All

Can anybody help me with a site or online manual on how to get XBMC on the ATV Black to work with my HD Homerun box.  I went through the menu system and added a source but when I try to view it I get an error message and it tell me to look in the logfile (which I don’t know where this is).

Any asistance would be greatly appreciated.


Thanks in advance
