The problem with converting avis to dvd if the movie is over 2 hrs, you are going to get a warning that the movie won't fit on a regular dvd (which it probably won't after conversion). The easiest way to convert your avis to dvd is download vso divxtodvd and it should convert your movie to a VIDEO_TS folder. If after conversion the folder is smaller than 4.35 gig, you should be able to use Nero to burn the dvd. If not i would use nero recode (if its included with your version of Nero) or use Dvd Shrink to compress the movie. I'd use Recode because i think the compression is slightly better. The burner and software you're using is fine, but if you're using the wizard, i'd try burning without it. It looks more complicated but you'll learn more.
