 When mythtranscode is run with a non default profile it can throw a
 floating point exception during initialisation:
 {{{
 Program terminated with signal 8, Arithmetic exception.

 422         if ((ydiff / display_video_rect.height()) < 0.05)
 (gdb) bt
     new_display_visible_rect=..., new_aspectoverride=kAspect_Off,
 new_adjustfill=kAdjustFill_AutoDetect_DefaultHalf)
     at videooutwindow.cpp:484
     winh=0, codec_id=kCodec_MPEG2, embedid=0) at videooutbase.cpp:419
     winw=0, winh=0, codec_id=kCodec_MPEG2, embedid=0) at
 videoout_null.cpp:152
     framecontrol=false, jobID=-1, fifodir=..., fifo_info=false,
 deleteMap=...) at transcode.cpp:716
 }}}

 This is caused by display_video_rect.height() being 0.

 Attached patch.
