I'm starting to agree that the content looks invalid.  It looks like all of the
byte ranges are off by 1.  For example, in
http://www-itec.uni-klu.ac.at/ftp/datasets/mmsys12/BigBuckBunny/bunny_4s/bunny_4s_50kbit/bunny_50kbit_dashNonSeg.mp4
(MPD is
http://www-itec.uni-klu.ac.at/ftp/datasets/mmsys12/BigBuckBunny/MPDs/BigBuckBunnyNonSeg_4s_isoffmain_DIS_23009_1_v_2_1c2_2011_08_30.mpd):

the first segment (for the 50kb representation) starts at offset 863.  I
believe is should start at 862 -- at that point in the stream there is a four
byte size header (0x00, 0x00, 0x00, 0x18), followed by the STYP fourcc.

I will try to contact the folks that host this content to see what they have to
say.
