 \textit{SAR}= Storage Aspect Ratio (i.e media file aspect ratio)
 
+In practice, there can be a problem with anamorphic format rendering as desired because it does
+not use square pixels.  So, for example, FFV1 format in the mkv container will ignore the DAR
+(Display Aspect Ratio).  You can check if your media is anamorphic format using the \textit{Mediainfo}
+program.  If the Width/Height is 720/576 (=1.25) and DAR is 16/9 (=1.777) then you have non-square
+pixels.  SAR (Storage Aspect Ratio) is different from DAR and you have to use a workaround as
