Hi, a little help if anybody can, I just purchased Debut Professional in order to capture NTSC 8mm cassettes, and the audio is ahead of the video. I'm using firewire and a Windows 7 PC 64 bit, which does nothing else during capture and is even unplugged from the internet,. There is no problem with the audio when the the Sony TRV-725E camera plays the tape. During capture Debut does not show that frames any are being dropped. I have tried to record as .dv NTSC, as MP4 encoder H264 and as MP4 encoder MP4 with exactly the same result.
