If you want to convert an avi file to dvd-video format, I suggest using DVDFlick or FAVC, or AVStoDVD. Any one can be easily found using Google. For converting flv to dvd, try DVDFlick, as it has support for that particular conversion.
I’m most familiar with FAVC of those three, and it will produce excellent quality dvd video using the HC encoder that is included.
Burn to disk with ImgBurn, a free burning program that I use for virtually all my cd and dvd burning tasks. Read [B]the guides[/B] for burning dvd video at the ImgBurn forum.
The most recommended media around here is probably Verbatim brand…either -R or +R depending on your personal choice. If you have a particularly picky player, you might start with -R.
By the way S_S, DVDShrink doesn’t have native burning ability…it uses Nero or DVDDecrypter or, if you have the special edition, it can use ImgBurn.
