divx avi acts funny in vegas

i've encoded some avi using dr. divx and i open them up into vegas to edit them and some funny things happen:

1. the sound does not play (no peaks or anything, the audio is flatlined)
2. the sound loads 2x or 3x longer than the video.

anyone else have any problems with divx encoded video? any solution?

divx is not meant for editing ... also dont use VBR mp3 as the audio - if you MUST use mp3, use CBR only ...

use a lot more keyframes in the divx file than is the default (which also means higher bitrate) -- better yet, dont encode your video to divx and then edit it in vegas .. just load your video in vegas first ... you will see a lot of contouring noise in divx, much less in xvid and nero h264 AVC ..

Though i was running my own tests between DiVX, Xvid , QT Mpeg4 and Nero Digital AVC for HD 720p content and xvid looked better and encoded a lot faster than Nero, divx pulled in third in quality and could not match xvid or nero ...... nero seems better for D1 than for HD - with the default cinema and HD settings anyway ..

You need to use something like virtualdub or tmpeg to rip the divx file into seperate, full length streams. There are various tutorials on the web on how to do this sort of thing. The new streams should then allow you to work with the video normally in Vegas.

I use Virtualdub to firstly uncompress both audio and video.That way everything stays in synch and you don't lose quality.
Use a codec like huffyuv for video and set audio to "no compression (PCM)"
