What is the specific problem? I can try to help. You can call the VASST tech support line (my company) but it isn't free. Sony has free tech support, the number is on the card in your box. There are also the Sony support forums athttp://www.sonycreativesoftware.com
@Dse. I put the clips on the computer. You can watch each one of them fine. When I drag them over to put the video together one of them or some of them just comes out black, but it is still there on the other side and you can play it by itself.
You hear the audio when you first download it. Not when you drag it over. But you hear the other ones that come over. Not sure about the other but should it matter if 4 out of 5 come over fine? I am not changing anything in between takes.
