    server: Fix thumbnails for XBox 360
    
    If a video file needed transcoding for the XBox, it would not display a
    thumbnail because the generated url was adding the /th/ subrequest on top of
    the /tr/ request.
    
    This caused a "no transcoder available for WMVHIGH_FULL.wmv" warning as well
    as a failing thumbnail request.
