You should get a hold of the full version of Toast. Version 5 or 6 but for movies 6 is much better. All you need to do is drag & drop your movie(s) onto toast, press the burn button & Toast will then convert the items before burning. Easy as pie.

Oh you need to open the LW Downld folder up. Go to LW's Library & select the Saved Files folder & any file to the right of it, then press the Explore button & the folder will open up so you can then drag & drop these files to Toast.
