    Which you may be interested to know is fixed following this ticket 
from last week:
http://cvs.mythtv.org/trac/ticket/626
This is fixed by svn rev 7837.  I didn't notice because I'm pinned to 
like 7738.  Anyone experiencing segfaults may want to svn update -rHEAD 
mythtv/libs/libavcodec/i386/mpegvideo_mmx_template.c to see if it fixes 
their problem.
