You can't use Bob with a 5200, as it won't handle a 60Hz progressive
refresh rate at 1920x1080. Upgrade to a 6200 or higher
(<URL:http://www.gossamer-threads.com/lists/mythtv/users/203862#203862>
and many, many other messages; search for "yeechang" and "6200.")
Meanwhile, switch to Linear or Kernel deinterlacing.
