MB STUDIO 8.72.9.8 and MB REMOTE 1.72.9.8 minor update

• Youtube: AVC format video download preferred (as some GPUs still don't decode the new AV1 video codec)
• Songs: fixed a malfunction of "Random song from folder" (if the folder did not exist or could not be reached MB STUDIO would crash)
• MB LIVE: Fixed a story list issue

MB STUDIO and MB REMOTE can be updated with this procedure: MB STUDIO - CHECK FOR UPDATES
