Why does the default output from my encoder not play with correct aspect ratio?

This issue is seen with the earlier releases (Rel 2.1.0 and before) of the H.264 BP encoder which was fixed in later versions after release 2.1.0.  However, if this issues is still encountered then you will have to configure the player to ignore the aspect ratio present in the bit stream.   For example if you are using mplayer then use the -noaspect switch on command line.
