Honestly, I don't see how lack of video tutorials prevents you from using the software 247 without interruption. If you have any specific question about how to use certain part of the program, or how to do something - you can ask here, or open support ticket, and we'll be glad to help.
It is not possible to create a one size fits all step-by-step guide, video or other, because RadioBOSS can be used in various ways and every user has his/her own tasks. One runs unattended internet radio, other occasionally streams live, someone else uses it for announcements in a gym or shop etc. and every setup is different.
