OK this may be a ghetto way to fix the problem but I find it works perfectly. When you get the error in Avid continue to import the file. What you get is the video with no audio.
Go to download.com and download a free program called AoA Audio Extractor Basic. Open AoA and drag the original file into AoA and convert it to a Wav file. You get the exact same audio without the video. Import your new audio file into Avid and lay that wav file in your audio track of your timeline. Line them up from the start and you have a perfectly synced audio track, same as the original.
