I have used http://www.longtailvideo.com/bits-on-the-run,http://www.influxis.com/, wistia for video hosting. Wistia didn't allow the finer control that we wanted to have. Influxis doesn't have the features that Bits on the Run has but platform usage for BOTR gets expensive. I was thinking of moving the videos to Amazon CDN. What are your thoughts and experiences with video hosting and are there any recommendations? Videos will be privately streamed to 100's of doctors offices.
