Please guys, I hope someone give me solution for theses issues, because for me Isadora without properly working Movie Player is useless and I think I spend my money for nothing.

 Mark Coniglio creator of Isadora here. As Juriaan said, please create a support ticket at https://support.troikatronix.c.. and include as much information as you can about the movies: resolution, whether or not you enabled Snappy compression, etc. One of our team will get back to you. Do keep in mind that this week is the Isadora Werkstatt gathering in Berlin -- all of the team are hear and it's a busy time. It may take 48 hours for them to get back to you.

Best Wishes,
Mark
