------- Comment #1 from Mark Nauwelaerts  2009-03-25 21:19 UTC -------
The documentation that gst-inspect shows for aspect-ratio might be slightly
misleading, but only for the case == 1, and unfortunately mainly due to the
necessarily concise nature of the cases' descriptions.  Slightly more elaborate
versions that should normally provide more clarity can be found in the man-page
for mpeg2enc, whose options are closely paralleled in the plugin. 
Unfortunately, it is quite misleading (and possibly even wrong) for this option
in there also ...

On the more technical matter; are you sure that an MPEG2 format/profile was
selected (?).  As the man-page says (and a further look in mpeg2enc code
shows), the specified aspect ratio is used directly for MPEG2, but it may be
translated/transformed for MPEG1, in which case 12 is one of the possible
outcomes.
