I am running Frodo RC2 on Windows 8 with some mixed results. Of specific concern though is the audio volume and how it declines over time. It appears that if you switch to another media application (e.g. iTunes or Netflix) and then back the volume drops off in XBMC. To restore the volume I have to delete the guisettings.xml file.
Not sure if this is of help but I am using the NextPVR add-on with my configuration.
