Hello, if you wanna convert and burn avi to dvd so that can be played well on dvd player, that's easy, first you should note, most DVD players only recognize video dvd format which include the VOB, IFO, BUP files, can't recognize separate mpeg file on dvd disc, so you'd better use a right software to convert the avi file to right video dvd format and burn to dvd disc, don't just convert to mpeg, but I don't think there's a free dvd burner software can do that well, I tried many free software before, none of them work well, some poor quality, some have watermark too, some even virus, so now Im using a cheap software RZ DVD Creator to do that, you can have a try, it can convert any formats video files to video dvd format and burn to any dvd disc, easy to use, insert a DVD disc into your computer dvd burner drive, run RZ DVD Creator, select the dvd burner drive as the target folder, drag and drop your avi file into the software, then press the START button, you will get a right video dvd which can be played well on the dvd players, of course, you also can use it to convert avi to mpeg, etc, you can yahoo or google search and download RZ DVD Creator, register version without watermark, but so cheap, hope it could help you..
