DVD Santa

hello All, I don’t know if this question has arisen before, and I’m really too busy to search the archives, so if it has been asked and answered, I do apologise. but time really is at a premium just now

I have the full version of DVD santa and have a problem with it. When I run the program, where 2 avi files are converted, ie disc 1 and disc 2, then try to burn to DVD, either with Santa or Roxio, for some reason, the second part of the movie always is burned to DVD first, and the first part burned to the DVD second. They are joined seemlessly, but always in the wrong order. Any one know how to correct thins.
