[Wikimania-l] editing Wikimania ogg videos and uploading to dotsub?

[Chuck Smith]

I'm happy we have .ogg files at http://wikimania.tw/streaming/ for the
video coverage, but they are so incredibly HUGE that they are
unviewable.  I've tried viewing them with VLC player on Windows and
Mac to no success... it seems that at a certain point my system runs
out of memory.  Does anyone know of an open source or freeware tool to
take a large ogg file (300 MB) and split it into reasonably-sized
smaller files?  I would prefer software that works on Mac, but Windows
software would also be acceptable.

Also, are there currently any plans to split the files and make them
viewable in an archive?  I think an excellent place to put them would
be on dotsub.com, so they could be subtitled in multiple languages for
the hearing impaired and those interested who can't understand
English.  Also, would we need explicit permission from the speaker to
release these videos under a Creative Commons license?

Best wishes,
Chuck
