I was trying to transfer the video from the cd-rw to the PC. After doenloading the file I was unable to open. Now The video was not available when I return to dvd camcorder to view the video

What type of file is it? AVI/MOV/MPG?

Its AVI

My camcorder is DCR_DVD708

You likely cut the file from the CDRW and pasted it elsewhere. You'll need to put it back on the CDRW and finalize it through the camera if that's how your camera system works.

My video cam is DCR-DVD708. I haven't pasted it anywhere. I just tried to open it in my PC but unable to open. I don't know what happened. Will ISOBUSTER work for this?
