I was able to use Handbrake by using desktop as the destination. When I dragged the video to the desktop, as you stated, and Clicked on encode the file, that file did not work..it there is audio but the video is only a single frame. not sure why...regardless, I do have another question about Handbrake, How do I Queue up all the videos rather than having to do one at a time? I looked on youtube for tutorial and I see that they are different format versions of Handbrake...they do not help with how to queue more than one video...do you know how? Thank so below is my version, ... and #2 and #3 are the versions that I see on youtube that show how to queue more than one video...you can see mine does not have the tool bar at top as in #2 and #3 which they use to load a queue

which they use to load a queue
