DVD Audio not matching Video when playing on DVD player

[Fatman]

Hi hopefully some one can help. I have searched and searched these forums finding similer questions but not the same.

I have just recently finshed downloading a Tv episode in AVI format, Which plays fantasticly on my PC.

Once I've burnt it to a DVD however and am playing it back on my DVD player I noticed ever so slightly the frames freeze.

By the time the movie is half way through, the audio is about 2-3 seconds ahead of the video which is really frustrating.

I am quite new at this and don't really know what to do. i am using Nerovision Express 2 on XP.

Also when at the stage of burning it says that I will be converting the file from NTSC to PAL. I always tick ok as I am in Australia as that is the format here. Could that be what is stuffing it up?
