I have taken a avi file, stripped the audio into wav with Virtualdub (which gives an error to do with VBR encoding in the audio). Then I use TMPGEnc to encode the video/audio(wav) to NTSC DVD standard. When I author and burn the file to DVD-R, it plays, but the audio breaks up/chops. Now, the original avi is encoded at 23.97fps, the NTSC DVD standard will only let me encode at 29.97fps (as opposed to 23.97fps with NTSC Video CD(film)). The video starts to "run away" from the audio i.e. gets ahead quite quickly - the video is about 2-3 seconds ahead of the audio after 15 seconds. Could it be that the video is playing at 29.97fps so effectively showing the video at 6 extra fps (video running slightly faster) while the audio cannot "keep up"? Also, the DVD information at the bottom of TMPGEnc shows audio at 384Kbps, if the audio is not encoded at this bitrate (originally) would that cause the problem? How can I tell what bitrate the audio is encoded at? Is this likely to make a difference anyway in the final product? I HAVE searched and searched again for an answer on all forums but have been fruitless, I have followed all of the related guides to the letter without success, anybody have any idea on this? The avi itself plays fine in media player and I have made 2xVCD from the file, these play perfectly (encoded at 23.97fps NTSC Video CD(film)). As the original avi is at a higher resolution than VCD allows, I wanted to burn this to DVD, the bit I have tested looks awesome - apart from the audio problems.

Please help.
