Got some mpegs from a friend I was going to edit up a bit. 1 file about 700 megs... I can't open the files in quicktime or anything even though I have the divx codecs, the apple quicktime mpeg codec ect... Downloaded program called mpeg streamclip. Opens the file, finds there is a time code error. Fixes the error and breaks and plays the mpeg perfectly. Allows me to export to any format and the audio drops out of synch again. I've tried visual hub, same or worse results.. Any ideas? I have no clue what they did with these mpegs, I tried opening them in Windows and windows media couldnt read them..
