What’s happening is your MPEG and .ac3 files are too large for DVD since DVDs are only 4.7GB.
If you’re using DVD SP to make the MPEG and .ac3, which I suggested you don’t do, then you need to go into DVD SP Preferences and lower the bit rate. Delete the files from your Assets tab (the files that were too large) and re-import your reference or self contained file so DVDSP can re-encode.

oops, sorry. I always do that. I meant “reference oR self contained”
If you’re getting an error when you bring a reference or self contained file into DVDSP, go into DVD SP Preferences. Make sure the Project, General, and Encoding panes are set up for SD DVD.
The best thing to do is make your MPEG and ac3 files in Compressor, and then bring THOSE files into DVDSP. Just because DVDSP can also convert to MPEG too, doesn’t mean it’s the best tool for the job.

You should export an FCP reference of Self-contained file with current settings.
Bring that file into Compressor and apply the “DVD 120 minute Best Quality” settings.
Compressor will then create an MPEG and ac3 file. Bring those files into DVD SP

I think it’s strange that you are seeing a difference between the reference file and self contained file. There should be no difference in image quality. The only difference is the self contained file is an actual video file, which explains the large file size, and the reference file is just instructions that the software reads in order to find the source media so it can do it’s thing. You should get the SAME results whether you bring a self contained or reference file into DVDSP.
I don’t have an answer to why one is working better than the other. But if the self contained file is giving you better results, then just stick with that. Usually the choice between using a self contained file or reference file is just a matter of preference, not a matter of right and wrong. The only time you are wrong is when you take a reference file to another computer that doesn’t have access to source media.

Here’s that video tutorial I said I was going to make:

It’s only for web compression though. DVD compression is coming soon

Alf,
What is the resolution of your tiff files. I know FCP doesn’t like doesn’t like really big images. Ideally your tiffs should be 72dpi and the pixel dimensions should not exceed twice the dimensions of your canvas unless you absolutely need to. Does that make sense?

I was actually going to make a video tutorials on these two issues for my blog, but I’m sure someone will beat me to giving you the proper info before I finish. If no one does, I’ll be sure to post a link in this thread.

In my opinion, you should use Compressor. While DVDSP can compress to MPEG and Quicktime can do compression as well, just because they can doesn’t mean they are the best tool for the job.
When you conclusion that the MPEG file Compressor spit out for you didn’t live up to your standards, what were you using to view the video. I hope you burned a DVD and viewed it on a TV.
Also, what have you tried for your web export. I always use H.264 compression, but there are some things you have to do to ensure you still have a nice image with a small file size.

Here is an article on capturing HDV as ProRes:
https://library.creativecow.net/articles/poisson_chris/hdv-prores.php
Also, you only need capture your HDV as ProRes because HDV is 8-bit. You will gain nothing by capturing as ProRes HQ. HQ is ideal for 10-bit sources larger than 1920X1080.
Now, I’ve never captured HDV as ProRes, but I think you will be fine capturing through FW800 to one of those G-Tech G-RAIDs that are set up for RAID 0
