Excerpt from DCSubtitle file:

<?xml version="1.0" encoding="UTF-8"?>
<DCSubtitle Version="1.0">
  <SubtitleID> d3d2b53b-b02d-4b69-8840-aa05de8c53fd </SubtitleID>

I am going to test if this causes problems while playing back on a real server/projector tomorrow. But this DCP has played at som major festivals (TIFF for instance) so I doubt it.

Also note that there is leading and trailing whitespace in TI:s example of SubtitleId usage on page 11 in the spec: http://www.dlp.com/downloads/pdf_dlp_cinema_cinecanvas_rev_c.pdf

Tested in the field on a Dolby DSS200 + Barco DP2K-20C. Subtitles rendered without problems.
