Just wanted to report a strange bahaviour of iHDSim when having specified multiple audio languages for a title.
WORKING:
<TrackNavigationList>
<VideoTrack track="1" />
<AudioTrack track="1" langcode="en:00" description="English 2.0" />
<AudioTrack track="2" langcode="de:00" description="German 2.0" />
</TrackNavigationList>
NOT WORKING:
<TrackNavigationList>
<VideoTrack track="1" />
<AudioTrack track="1" langcode="de:00" description="German 2.0" />
<AudioTrack track="2" langcode="en:00" description="English 2.0" />
</TrackNavigationList>
There are no problems reported by the Validator but iHDSim crashes as soon as this title gets started.

iHDSim catastrophic failure

Do you have your default language set to EN in the playlist HDiSim doesn't support multiple audio tracks, so probably what is happening is it wants to pick EN (assuming it's the default) but it can't because it is track #2.
Unfortunately iHDSim is unlikely to support multiple audio tracks any time soon.

Btw. there is no difference if I set defaultLanguage to EN or DE. In both cases it crashes with a "missing file" message in the status bar if the first audio track is not labelled English.
