017e234c20 avcodec/vc1: fix mb_height for field pictures 
Fixes ticket2531

or interlaced content. The alternative would be to detect a change
and reallocate.

0f02ea0afe libavcodec/dvbsub: fix for Display Definition Segment

display window parameters are given in this order XMin, XMax, YMin, YMax
if  display_window_flag is set, but here this is not the case.
As a consequence the DVB subtitles are not displayed upon some videos.
