Compressor only exporting left audio channel in AIFF! Please help!!

Question

Hi, I just realized that the files that I have been exporting using compressor have been only exporting the left channel of audio. I am not sure what the problem is and would appreciate any help anyone could give me, as I'm on a big deadline and need to solve this ASAP.
The way I've been doing it, is I right click on the sequence name in Final Cut Pro and select Export > Export Using Compressor. Then I selected the DVD Best Quality 90 Minutes option. The AIFF file that is created seems to only have audio in the left channel. The original files themselves are definitely stereo, and play both channels in Final Cut.
I really don't understand. The Inspector within Compressor shows this information for the AIFF file:
File Extension: aiff
Estimated file size: unknown
Audio Encoder: 16-bit Integer (Big Endian), Stereo (L R), 48.000 kHz
It says Stereo, so I don't know what the problem is! Please help!!!

Glad I could help.
Sorry for being a bit unclear, and actually misguiding you a bit on the reference files. Reference files are referring to the original media/render files. As long as you do not change the actual media/render files, you should be able to do changes to your FCP project. If you have not rendered before you export a QuickTime Movie reference file of your sequence, it will render on the fly and put the render files inside the reference file with the audio.
I would recommend reading more about self-contained files and reference files in the Final Cut Pro User Manual -> Volume IV -> Part III -> Exporting QuickTime Movies -> Choosng the Type of QuickTime Movie to Export
From the manual:
Choosing the Type of QuickTime Movie to Export
You can create two kinds of QuickTime movies with the Export QuickTime Movie command—a self-contained movie or a reference movie.
Self-contained movie: A self-contained movie contains the video and audio media— all of the data used to create your movie is within a single file. This single file can be safely and easily copied to another computer without worrying that you need other files to play it back.
Reference movie: A reference movie is a very small file that contains pointers, or references, to all of the captured clips used in your sequence. The actual media is located in the original media files. If you rendered your transitions and effects before creating the reference movie, then there are pointers to your render files as well. Otherwise, all of your transitions and effects are rendered using the current level of compression, and then embedded inside the resulting reference movie, increasing its size. All audio tracks, mixing levels, cross fades, and audio filters are rendered and the resulting stereo or mono audio tracks are embedded in the reference movie.
Exporting a reference movie saves time, since you don’t have to wait for every frame of your edited sequence to be duplicated. It also saves hard disk space, since pointers to other files require little space. Reference movies are particularly useful when outputting your sequence for compression using a third-party compression utility.
However, reference movies are not very useful as a means of delivering video files to other people. If you give someone a reference movie, you must also give them the original video files associated with that movie, which can be complicated since you may not know where all the referenced media is stored on disk.
In general, exporting reference movies increases the risk that the movie may not play back. Reference movies are best used when you have short-term uses for the exported movie file, and you only plan to use them on the system you exported them to.
