Captioning OGG files is still kind of 'tricky', but certainly worth
investigating further. I might suggest you start here:

Silvia is one of the lead engineers working with Mozilla towards
implementation of the <video> element in HTML5 (which currently does not
specify *how* to include captions, but we're working on it), and is likely
one of the most knowledgeable people I know when it comes to OGG files
(which are already supported in FireFox 3.6, Opera 10.5 and Chrome
browsers using the native HTML5 <video> element.
Moving forward (i.e. hopefully in the near future), captioning for OGG in
HTML5 will require either .SRT files or a profile of .DFXP (.XML)
time-stamp files, and will likely take a pattern along the lines of what
is described here:
<a class="moz-txt-link-freetext" href="http://www.w3.org/WAI/PF/HTML/wiki/Media_TextAssociations">http://www.w3.org/WAI/PF/HTML/wiki/Media_TextAssociations</a> (there is also a
proposed JavaScript API for extracting captions bundled inside a media
wrapper such as OGG or H.264 -

PLEASE NOTE: This is very much a work in progress, and like many aspects
of HTML5 is subject to change at any time, so this is for this group's
information only and is NOT a recommended technique at this time. As well,
these particular proposals have not even advanced to the larger HTML5
Working Group at the W3C, but are draft proposals at the Accessibility
Task Force level (for those who care about such things). That said, it's
exciting and promising, and we may even start seeing implementation as
early as this fall, so stand-by for details.
