I have tried everything. Vegas, Pinnacle, Ulead, Premiere, etc. ANd in all of them, once I get about 1-3 files playing in the preview window, it plays at about 1 frame for every 3 and a half seconds. It has only not happened in windows movie maker and Nero, but those programs don't have very good editing features at all. Even those will begin to skip after a project of about 3+ minuets. If anyone can help me, I will be very happy, and I am open to my machine not being good for this.
