Home Media Center Up and Working

Did a temporary fix to the script and now the Home Media Center is up and working.  Streaming a movie from my DVD collection as I write this.  Quality is good.  There have been three or four buffering events so far.  Only other issue is screen size.  If I play the same movie on the Blu Ray player, I get full screen.  Streaming through the Roku gives a standard screen size.  There are some choices in Handbrake that may solve this problem.
