My boss has just modded his xbox and got XBMC on it. But he's having problems getting video to play properly. He has access to both SAMBA and XNSP(?) shares and can ftp to the box getting a minimum of 12Mb/s (wireless) but usually more. But when viewing divxs, there is sometimes stuttering. Sometimes at the beginning, sometimes not for 20 minutes. These are low bitrate (eg 450MB for an hour). So transfer speed doesn't seem to be the issue, but any ideas what might be? He's wired the xbox into his wireless router/modem, and his PC has a wireless usb stick in it. Using windows firewall and CCX gui lite (enabled through the firewall). The stuttering happens whether using ccxgui or samba shares.
