[Walter Miale] " It lacks clarity and transparency"
What in the world does lacks transparency mean?

[Walter Miale] "uncompressed dv"
There is no such beast to begin with, DV is very compressed for an editing codec 5:1, as well as low color space 4:1:1

but the answer is if you are authoring a DVD it will have to be m2v video which is even more compressed then DV.

To get the best results of graphics you need to do one of two things, Not place them within a DV timeline or codec. Uncompressed 10-Bit or ProRes is much better.

If you have to place them in a DV timeline because of your workflow, do NOT render the timeline. Export the timeline Using Compressor. IF you can use a high bit rate (6-7 Mbps) use CBR method. This will give you the best results. Note, FCP and Compressor will be tied up while doing the encode but the CBR will be much faster. Make sure you encode the audio as ac3 to give the video more bitrate and will playback better. There are post on how to encode ac3.

[Walter Miale] "Would it help to cut a Blue Ray disk?"
Not if you are starting out with SD DV footage, a waste of time and expense and...

[Walter Miale] "Can Blue Ray disks be played on most computers? "
NOPE, computer has to have a bluray drive and they are only on a small percentage of system.
