When in edit mode as long as I am viewing the video I have audio. If i edit such cut and start from there i have no audio unless i return to the start, this began after my first update. If i did not have the download version I would be tempted to uninstall (If I had the install disk) and reinstall. I think i have tried everything else. What can i do? My operating system is windows 7. I import the video from my DVD drive and then edit it. I repeat, I did not have this problem before my first update. I keep video it is the audio that is lost. If I do no editing it will play all the way. J.B. Beasley
