I use Cakewalk by Bandlab for Sequencing, but when the grandkids come it's my karaoke player. It worked perfectly running with windows 10. I now have windows 11 everything runs smooth until I try the karaoke files. The audio is perfect, but the video is in frames and out of sequence. I know it has to be a simple fix I just don't know what it is. Is there anyone out there with a fix.
