A couple of things. When you exported from FCP you should Export Quicktime Use Current Settings and not check Recompress All Frames.
I’m assuming that DSP is DVD Studio Pro. While DVDSP allows you to encode you shouldn’t use it that way. Use Compressor. Also your data rate is way to high for a DVD. The maximum allowable rate is around 10mbps. In practice most people set the upper limit to 8mbps or less. That allows space for the audio. If you use ac3 (and you should) you might be able to push a but higher, but you don’t need to for excellent imagery.
In Compressor choose the DVD: Best Quality 90 minutes preset and you’ll get very good images the way it is. Also in Compressor is an ac3 preset, but you’ll have to change some settings for it to work properly. Highlight the ac3 preset and in the Inspector click the Encoder tab and then the Audio tab. Make sure the data rate is 192kbps and change -27 to -31 in the Dialog Normalization field. Then click the Preprocessing tab and change the Compression Prest to None.
Once your files are encoded import them to DVDSP and you should be good. You can find more info about this in the Apple DVD Studio pro forum on the COW.
