Added a first play mpg (audio and video together) to the project but wanted to trim about 8 seconds of black. So I set a new in point 8 sec in. I Prepared and burned a DVD and audio was 8 sec out of sync. I tried again to prepare and burn but this time I put the in point back to the beginning. The DVD again was out of sync. THe video was all there (including the 8 seconds of black) But the audio started right where I wanted it to on the previouse DVD. I know I'm doing everything right. If DVDA3 lets you set in and outs then it should work on both audio and video, and keep them synced. I hope there is a fix soon. My third and succesful attempt was to close and reopen a new project (basically start from scratch )and not mess with the in point. The DVD is in sync but with that darn 8 second of black. I'd hate to have to re-render a complete video just to trim the begininng.!!!
