Basically got win7, win live with windows movie maker. I have a music video that i want to edit that is 1 hour long but when i import into movie maker it says that it is less than the original length and when you preview it, it finishes short of the original video. The really odd thing is, when you are previewing, if you click on the slider to take it back to a particular point in the video,lets say 15 mins 10 secs it shows you the missing video where it shouldnt be, then click again, and there is another part of the video that wasnt at this time point. What the hell is going on. Hope you can understand what i am trying to explain...... HELP.
