DVD (created with iMovie and burn with Toast) but sound not properly synchronized if watched in France
I have created a video with iMovie on a Mac computer, then burn a DVD (with TOAST) to be used with a standard DVD Player.
I have tried the DVD with an ordinary DVD Player and TV in Italy and work fine, but then I have send the DVD by post to France, but the sound it is not synchronized with the image of the recording film (and has been used on an ordinary DVD Player and TV).
