This video has display_extension which is giving a display_horizatal_size of
720 and display_vertical_size of 576. The PAR is calculating in 1.0 based on
this instead of the default width of 352 and height of 576 .
(default widhth/height : valued parsed/calculated from SequenceHdr and
SequenceHdrExtension)

But in 0.10 there is no parsing for display_extension and which will use the
default width of 352 instead of 720 for PAR calculation.

It seems that the mpeg2dec is giving the PAR 16/15 in both 0.10 and
1.0.(pipeline with out parser element) . But avdec_mpeg2video/ffdec_mpeg2video
is giving 24/11 (with out parser element).
