Thanks Brian, I have not thought about that piece of software for awhile but have it on one of my computers and will give it a run in the morning.
For some reason if I export as an AVI rather than using the MPEG encoder in Premiere it seems to not loose sync. The only trouble there is than I am taking the video portion through an extra change and so loose a bit of video quality to gain the audio quality.A trade I would rather not make.
Thanks for the suggestion and I will post the results in the morning.
