Ok i'm not associated with the build 666 or pre releases there after, however i can provide a detailed summary of bugs i have found and collaborated from others:
BUGS:
My Videos, My Pictures thumbs not working
Answer: New thumbs directory will solve this, it has been auto created by the T3CH.
Pictures not previewing
Answer: Still no fix, however better luck if not playing with a visualization running
Videos not playing
Answer: Still no fix if you have this problem, however see previous bug and refer to remove any previous builds.
System Blade Lockup
Answer: More people in common are having this one, as of the time writing this no fix has been found. Though i would say to fix this would relate to somehow the settings being saved and not deleting any previous preferences.
Logo load only
Answer: Having this one personally, you must of activated the Master Lock and currently not supported in this build. I am referring that you will only see the XBMC logo/lightning logo then either a resume loop function like action will occur or power off.
No Remote access:
Answer: Somehow unknown but post detailed problems and someone will help you if you make sense.
Kai freeze
Answer: Check as usual all network settings of both clients/server or any other nodes if applicable.
Any other problems please post in the right place. I am really looking forward to contributing any fixs to this build as i think the MC360 skin is the best of any skin in any XB-App/Dash.
Also note the use of the Shortcut must use for dash. Also to know i tried using other shortcut makers and they failed, Team UIX's shortcut no problems.
