We would like to help you have as enjoyable and frustration free experience as possible, but please keep in mind that 1) we are not computer technicians, and 2) there’s no way for us to know exactly what’s going on with your computer.

However we likely have had  every problem that you could have with computers and videos. Below are some resources that have helped us. We will continue to add more as we become aware of them.
