I have been using Vegas Movie Studio HD Platinum 10.0 for years without issue. Previously I uploaded only video from XM DVR Pro camera MPEG2 digital recording (whatever that means - I hope it is relevant). I switched my video source to my Toshiba lap top with windows 10 home. The video playback is good; however, when I export that video into my Vegas Platinum 10.0 the audio and video are out of synch. Why is this happening? How can I fix the problem?
