height or aspect change is detected -- not MpegPreProcessPkt gets called

One more tidbit of information before I call it a night.  This may
have reached Heisenbug status.  Check the new patch I uploaded and
look for the Heisenbug comment.  For me, I get stuttering with those 
four VERBOSE calls #if'd out and no stuttering with those VERBOSE calls
#if'd in.
