Yes, VLC shows the videos in Windows 10. I was hoping for default Windows 10 video player support, but VLC is certainly a workaround.
Another reason for the suggestion is that QMC2 doesn't play the VideoSnaps in Windows 10 without the proper Codec set. When I installed the Shark standard codecs, QMC2 shows the VideoSnapS videos, but they are upside down and backwards!
Thanks for all that you do in order to create all of the MAME support files!
