DVD Import Creating Out-of-Sync Files

We recently installed DVD Import version 4.5.9 build 2. At first, the program was working well, and in fact seemed like a huge improvement on the previous version we had. The importing was much faster, and the stereo audio on the files was much cleaner.

However, late last week I noticed that a couple of programs had lip sync problems. The sync is off from the very beginning of the program, it does not get better or worse throughout. The original discs test out ok. The problem was big enough (I estimate at least between 1/2 to 1-second delay on the audio) that it was immediately noticeable on the air.

What would be causing this to happen, and how do we best address this issue? DVD Import is a critical part of our workflow, but we can't put on programs with this kind of problem.

I have one of the offending mpeg-2 files up on an ftp server if someone would like to look at it.

Thanks!
