Hi i have a Sony Cibershot that out puts the movie format in MPEG. the movies play on quicktime no problem but when i import them into imovie for editing there is no sound. i have tried to convert it using quicktime pro into every other format possible and for some reason every conversion results in the the loss of the audio. I have an older cannon that outputs video in AVI format and that works just fine with the imovie. Any Ideas?
