Ok, I am REALLY hoping you can help... I imported my DV footage using IMovie on my PowerMac G4, with OS 10.2.8 I know have IMovie HD on my new MacBook Pro I opened up the movie to do some editing...and a alert box says "opening this file may cause file not to open in older versions of imovie" I clicked ok to proceed. Now I play the clip (without editing yet) and most of it is scrambled! ANyone experience this also? How can I fix it?
