Question Divx frame rate conversion with a/v sync?

hi all,

i have this divx movie that i want to convert to dvd, but it has a frame rate of 23.976, so it is not compatible. So i want to convert it to 25fps, and that would obviously give me a/v sync problems. anyone know how to convert without loss in synchronization?

Why would that "obviously" give you a sync problem?
What are you going to use to convert it, and what are you going to use to encode it?

i am converting the video frame rate through virtualdubmod, which says that fram rate conversion will cause sync proglems... i think all i need now is a program that can convert audio frame rate from 23.976 to 25... can besweet do it?

Or Audacity, or Goldwave, Soundforge, Wavelab...
Why use vdub to convert framerate, let your encoder do it.
Depending on the video, you shouldn't get jerkiness, it's only 1.024fps difference...
The easy way, is to extract audio, convert video framerate in vdub, encode video to mpeg, then adjust sync during authoring, or you could simply use Goldwave's timewarp feature.
I absolutely hate besweet, so I can't comment on it's ability to convert fps.

thanks a lot
i tried besweet, and muxed the video and audio back together, and worked perfectly. i've been doing mpeg-4 encoding for like 2 years now, but only started dvd encoding couple of days ago cause i just got a new burner
