 | Compressor/Distributed Processing weirdness - .m2v end up shorter than .ac3??

Hi everyone, I have a weird issue going on here, and I haven't been able to find a solution. I'm hoping someone else here has dealt with this in the past and can enlighten me on how to fix this.
I'm cutting a short film right now (about 19 minutes in length), 1080p 23.976, using Avid Media Composer 3.1.3. To make DVDs of the film for client review, I export a quicktime reference from Avid and use Apple Compressor to encode the video (using the apple preset High Quality 90 min DVD).
Here's where things get weird. I have my Mac Pro networked to another Mac and have set it up for distributed processing. Encodes fly with this setup, more than twice as fast. But, lately i've noticed something weird. The resulting .m2v from Compressor is about 1-2 seconds shorter than the.ac3 file. The result of this being that the audio starts out in sync, but by the end of the show, its noticeably out of sync.
If I don't use distributed processing, and encode the video with only one computer, the resulting .m2v is the correct length and everything stays in sync. I've been using this option, but it kills me because it is so much slower.
Has anyone ever seen this before? Any solutions/workarounds? Any help or insight is greatly appreciated. (PS, both computers are running the latest version of compressor with Quicktime 7.5.5)
Thanks
Tanner
