Whats a free DVD burner?

The process called encoding, most DVD players only recognize standard video dvd format which should include the VOB, IFO and BUP files, not only separate VOB files, so if you want to play the burned DVD well on any DVD players, you'd better use a right software to convert the avi format film to right standard video dvd format then burn to DVD. But for all your requirements(like add chapters and subtitles, etc.), I don't think there's a free DVD burner software can help you, cuz I tried many free softwares before, but none of them work well, some poor quality, some even virus, so now I'm using a cheap software RZ DVD Creator to do that well, it's fast and easy to use, I think it can fit all your requirements, it's easy to use and provides many dvd creation features to make and burn the professional DVD from any formats films, with it, you can easy customize the nice dvd menu, such as chapter menu(split chapters), it can customize the "Play All", "titles/videos selection", "chapters/scenes selection" screens and buttons on dvd menu, can customize dvd menu background video, picture, music, text, etc, it also can add srt subtitles to any formats films, it can convert any formats films or videos and srt subtitle files onto a video dvd with subtitles, and burn to any dvd disc(DVD+R, DVD-R, DVD-RW, DVD+RW, DVD-R DL, DVD+R DL, etc), and you can play the burned video DVD well on your DVD player with the customzied chapters and subtitles. You could yahoo or google searcha nd download RZ DVD Creator, very cheap, hope it could help you.
