hi, I tried several methods to convert a .mov file to .mpg, but none really works, and google didn't help me in that case. ffmpeg seemed to me the best choice, but I get: Invalid data found when processing input As it seems to work for other people, I suppose that some ffmeg codec is missing, but which one? (I can read the .mov file with vlc, mplayer, ...) best regards, -- Pierre Frenkiel
