Dragon's Lair, Dragon's Lair 2 and Space Ace frame files

You might have noticed that playing these games the videos are not perfectly synched. Some are cut or are missing pieces, other show a bit of the next scene. I suspect this is happening not bc something is wrong with the video itself but bc the framefiles Daphne is using is not the 100% correct ones ie they start reading too late or cut off too early.

Any idea on how to fix that?
