I use the Ulead Media Studio Pro 6.5 and the Ulead VideoStudio 5.0 for my video editing. My captures are all from MiniDV through Firewire with no dropped frames. I preview my finished video on the screen with no problems. The only time I have problems is when I want to record my finished video in AVI back into my MiniDV camcorder. What I get is 3 seconds of video and then the blank blue screen and as it goes, the video stutters in a jerky motion. This goes on and on.
