Hope someone can help: I am using Ulead Movie factory with all the latest patches- to create a DVD. The disc plays OK, but for each chapter of the 50 minutes, the sound gets progressively in front of the video, as the track plays. The original Mpeg file on the PC plays fine, so I am supposing that there is a problem in the Disc Image file creation - am I right ? It's authored from DV tape- audio is 48KHz, 16bit, video is AVI open DML type 1 - 25F/S, 24 bits, 720x576 frame size. I have followed all the advice - eg. switching off screen savers, enabling DMA, disabling scheduled tasks, adjusting for best performance etc, etc. My PC is 3Ghz with 120 HD that is defragged. Could any one help please as I am now stuck ? Many thanks.
