Firstly you have to help us by telling us what frame rate you edited in, what audio system was used to make the final mix file and how you imported it into FCP.
A search of this forum will also show you that this is very common problem and has been answered many times.
My recommendation is to firstly convert the file to 48Khz aif and import that instead. FCP is trying to be smart with wav files and so often it labels the file with a frame rate that is incorrect. It may also be that the problem is in the frame rate used by the audio system. This commonly happens when 23.976 and 24 frames are confused

HDV is the same data rate as DV. How long is your program because 25-30 gigis of HDV is approx 2.5 hours long? My guess is that there is a mismatch between sequence settings and the output QT file, which may also mean your sequence settings aren’t the same as your codec.
Also when you export a self contained QT, make sure your settings are “same as sequence”. Finally how are you judging the QT file. If it is in quicktime player then depending on your version of quicktime, you might not have optioning the display settings for hi quality and FCP compatibility.

Check you sequence settings and see how many outputs are mapped in FCP. Chances are it is already mixing down to stereo. If not, then make sure that the track output patching on each track is to Channel 1&2 output. The way to check is to right click on the audio tracks near the lock icon. The manual is also very helpful in explaining audio patching in FCP which is really very basic.
If you are making a ProRes master clip then Linear PCM is what you want. AAC and all the other audio compression codecs that you mentioned are useful for lower res web files, not a hi res master file.

Matrox also have an H264 accelerator.

That behaviour is unusual. To manage your preferences and to readily trash and restore, download the free preferences manager from Digital Rebellion. https://www.digitalrebellion.com/resources.htm
Also repair disk permissions. Where are your render files going? How have you set up your scratch disks? What are your sequence settings and do they match the clip settings exactly?
Next how did you install FCS3 and the OS. Was it a clean install or overwrite of an older OS & FCS2? All these may be a factor in why your system is behaving abnormally. I have the same FCP7.0.1 and Snow Leopard and I can assure you I have nothing like this behaviour.

Frank, have you upgraded to 7.0.1? Have you tried the usual maintenance jobs (trash preferences, repair permissions?).
When posting about problems it helps to say which version you are running and what you have tried to remedy the problem if anything. It saves us asking endlessly the same questions. “Stunning silence” is often the result of regulars here just not wanting to have to ask the basic questions over and over.
Help us help you. It’s just a basic courtesy.

When making a graphic for a standard def sequence, then it is best to make the graphic interlaced. Your DV sequence is interlaced so try exporting the graphic again from motion matching the sequence settings of FCP.
I am not sure why you made the graphic in HD as you are then using FCP to scale it down to SD interlaced. Also you are better to finish in an uncompressed or ProRes final SD sequence as DV is a poor codec for graphics and adds another layer of lossy compression before making the mpeg for DVD

What version of FCP? This sounds like a bug in the early versions of FCP6.
If it is 6 or 6.0.1 then try updating to 6.0.6 which was the final version of FCP6 and didn’t have that and many other bugs.

Do you have any large stills in the timeline? A common problem when trying to render images with pixel aspects exceeding 4K is getting that error message.
Check the timeline and if necessary replace any files with excess pixels with reduced versions. Otherwise it may be a corrupt file. Try rendering small sections of the timeline and see if the error appears on particular clip.
