Training Videos

Not sure if I am in the right forum, but I would like to create some training videos, but don’t have an idea with how to deal with the following items:

  • Since I don’t want the videos to be copied, is the flash the correct (or only option)?

  • How do I protect the content from piracy? I guess similar/same question as above.

  • Just to get some general direction, how would I handle creating a login and/or having a link expire.

Or just perhaps point me in the right direction with how to go about creating paid online training video.
