I have been using My Screen Recorder to produce training videos. My current set are of limited interest and only really relevant to my training exercises.

However I am now contemplating creating a full training suite which will be of significant commercial value and liable to be duplicated and resold. The ability to protect these is of great interest. I see "Pro" offers the ability to write exe files with incorporated viewer rather than using avi files as I do currently. Can anyone advise me whether this avenue offers me a better opportunity to make things secure? I found a usb dongle device which seems to encrypt files and act as an indispensible key. Any other ideas?
Many thanks
