Anyone had any rendering problems with audio and video? Whenever I render my final project, my audio gets out of sync with my video. At specific points during the movie, the video skips for about a millisecond, and then the audio loses sync with the video. Any ideas on how to fix this?? I've re-installed Vegas about 8 times, upgraded to 4.0c, and still no fix. I really need a solution. Is there a known issue with DirectX9? My machine is running Windows XP Pro with DX9. I've got a Radeon 9700 Pro, and a Sound Blaster Audigy 2 Platinum. All the drivers are fairly recent, I'm one step behind in the Catalyst series, and my Audigy drivers should be the newest. Any help would be greatly appreciated!!
