Why is my audio and video out of sync when i use avi2dvd

Hi all,
I am using avi2dvd software to convert my avi files to dvd. I burned some converted files in dvd. But the audio and video out of sync on that dvd. What is the problem? Anyone?

Thank you for all suggestions.

Check if the data files are NTSC or PAL. You need to change such things when converting this. If any other program or application was running when you are burning dvd, then it may cause this problem.

Try burning your dvds with Nero. NeroVision Express is a pretty good program. It creates all types of disks with many file support. It may be the avi file that is causing the problem. It may be corrupt.

If your encoder saves the output to the hard drive and verified. Check the output is OK and then only burn the disk with the burning software. Use any other software like dvd flick. If you are trying to combine two avi files with srt file together then set the second half of the combined srt file and applying Edit/Timings/Set delay. Make sure everything is in sync and then use avi2dvd to encode this now one-part movie into dvd video.
