I’m sorry for the inconvenience that you have experienced here.
Now, lets start with this being the first report of this issue with these videos.
Since you are the first reporter, then there is good reason that nothing may have been done to fix them in the past.
After I received this notice from you I have been able to check the videos and after watching all the videos to look for stoppages I can not confirm this behaviour.
This is something that we had in the past, usually Macs, usually behind a firewall or router, but it has been a long time since we have had complaints.
Generally if you have issues then you need to use the http streaming method…the catch here is that it is slow loading because it must load the video first…which could be around 150mb
Also, please remember that any time you have questions not covered by the videos you have access to Cineversity Q&A where you can ask any question you want about CINMEA 4D and have them answered by Dr. Sassi, or myself. So your answers could have been a forum post away, as this is included in membership.
Now as far as you issue goes, if we are to explore the issue more it would most likely mean that your involvement would be required, is it ok for us to email you if that is needed to look into the issue?
