Error playing MPD

I am trying to use my own mpd with your TAPAS Player. When using your suggested MPD things work fine, but I receive the following Errors:

Looking at both MPD files I see the following for any one representation:
<SegmentTemplate duration="2000" initialization="$RepresentationID$/init.mp4" media="$RepresentationID$/$Number$.m4s" startNumber="1" timescale="1000"/>
<Representation bandwidth="1018420" codecs="avc1.4D401F" frameRate="24" height="480" id="V4" scanType="progressive" mimeType="video/mp4" width="1128"/>
<Representation bandwidth="869460" codecs="avc1.4d401e" height="480" id="3" mimeType="video/mp4" width="854">
<BaseURL>car-20120827-87.mp4</BaseURL>
<SegmentBase indexRange="708-1183">
<Initialization range="0-707" />
</SegmentBase>
</Representation>
Does your player only accept this one certain form of encoding?

Hi there,
Indeed I've encountered the same problems when working with TAPAS. In fact it does not accept all variants of MPEG DASH manifest files. I've created my test sequences with mp4box
and the following parameters:
mp4box -dash 2000 -profile ondemand -single-segment your_input_file.mp4
TAPAS should be able to work with those.
