After building a new machine with Premiere CS5.5, using NVIDIA Q4000 card, I'm having troubles wioth my audio being out of sync. I am exporting DSLR footage which the same sequence was previously fine on export on my old computer. Now, when I export, the audio is a few frames out of sync. There's something really funny going on. When I play the same video file in Windows media player, it seems to be in sync. When I play it in Quicktime, it's clearly out of sync. Also, when I upload it to Vimeo, it's out of sync as well.
If you'd like to see the specs of my computer, you will find them in this post:

When I export the same file to Mpeg DVD, it seems in sync. Does this issue sound familiar to anyone?
