Simon you have probably sorted this out by now but just for future reference I will post this anyway.
If your problem is simply that the audio and video are out of sync then there is a quick fix in Premier Pro. Click on the file in the timeline to make it active then right-click on it and choose UNLINK. This will make the two independent of each other. Then you can just drag one in the timeline until it is in sync with the other, might take a couple of tries to get it perfect. Once you are happy with it select both assets and right-click on one of them and select LINK to rejoin them.
