This is part of your problem.  Bob is not working.

Use 'xvidtune -show' to print what modeline you're actually using; look 
in the frontend log (with --verbose playback,general) for "Refresh rate: 
xxx, frame interval: yyy".  Refresh rate (in usec) has to be smaller 
than half frame interval for bob to be able to work.  Adjust your mode 
(choose a new one, or change the first number which is the pixel clock 
in MHz) until it is.
