I use AVStoDVD, DVDFlick, (you'll also need IMGburn with these ) or DVDStyler, all free. But it depends on the AVI, I found that some AVI's are containers for other formats.
I had trouble with the AVStoDVD no-install package, but finally got it working, might want to avoid the no-install, and DL the one with the installer. you'll also need to download and install the current versions of Avisynth, and FFmpeg, and place them in AVStoDVD's folder.
Avanti will convert some videos to Mpeg-2 and audio 48000Hz so it can be burned to DVD with the software mentioned above, also free.
Check out Videohelp for reviews, downloads, and guides.
Before I burn a DVD, I choose the option to make an ISO image of the DVD saved to the hard drive first, so I can preview the footage before burning to a DVD. Sometimes the audio is out of sync. or the menu is wrong.
I use VLC media Player to play the ISO image.http://www.videohelp.com/tools/sections/al...-dvd-convertershttp://www.videohelp.com/tools/Avantihttp://www.videohelp.com/tools/DVDstyler
Hope this helps.
