Best file format for burning DVD-R's?

Hi, I know this is sound and video sync problem(the sound was so out of sync), I met the same problem before, just because your video file is incompatible with your converter software(include any video converter, windows dvd maker, etc), so will meet this problem, to fix this problem, I think you can follow me to use RZ DVD Creator to help you, it can convert any formats video files to standard video dvd format and burn to any dvd disc(DVD+R, DVD-R, DVD-RW, DVD+RW, DVD-R DL, DVD+R DL, etc), and now I always use this software to convert and burn various video files(like avi, wmv, mpeg2 video files, etc) to dvd to watch well on my dvd player with right video and audio, and never meet this problem any more, so I think it can help you to fix this problem, you can yahoo or google search and download RZ DVD Creator, hope it could help you.
