audio/video sync, divx codec

I have a movie, separated into 2 .avi files. I believe the files were
created with the divx codec (about 720 MB for an hour of video). On
my DVD player, they look and sound fine. But on my PC the audio and
video are out of sync. I am fairly new to video editing but from what
I gather this is a common problem.
I want to combine the 2 files and get the movie onto a single disc. I
can convert the .avi's to pretty much any other format, with AVS. But
won't the sync problem remain? I've tried moving and stretching the
audio track with Audition, no luck. I don't know if I can sync them
up if I stay in the digital file domain, so the best way to get a
single-disc copy of the movie might be to just start over - play the
discs on the DVD player that keeps them synced, and capture that video
just like I'd capture a VHS tape.
Is there a predictable (and thus, a known and perhaps fixable) audio/
video offset that one might expect when using this codec? Is there a
package out there that is hard-wired for fixing a sync problem if it's
told what codec created the problem?
And on a more philosophical note, why is this such a common problem?
The people who write codec software must have known about sync
issues. I believe I read that the divx codec is from GNU? Isn't
their stuff supposed to be bullet-proof? Or, at least more bullet-
proof than most people's?
