Technology has a way of doing strange things sometimes...I wouldnt call it the work of a spirit unless it acts up very often and still does when you put a new tv/radio/pc in there. Or if also at the same time other stuff starts happening.
To a MA. Well sounds like everything went all right. I hope you wont have any "nasty" effects because of the ritual. And I hope that the spirit of your father (if it really was, I cant judge.. ) will stop trying to take your mom and you down with him.
I still think most of that flash movie is pretty fake though... .
(Glad you are sharing stuff with us though... )
*fujin that would be to you, sir*
