Srolling credits issues

I have an End Title crawl created in Photoshop, and brought into AE for a simple scroll for use in a 720p DVCPro HD project in Final Cut Pro. I've exported as an animation codec to insert back into FCP. The dimensions are as follows:

I've tried 2 versions - one with orange text and one with white text. While each looks fine on my computer monitor from within Photoshop and AfterEffects (I don't have a large external monitor), there seems to be both a lack of sharpness with both colors, as well as a breaking down of the orange when checking the DVDs made. ANY and all help is greatly appreciated:

Photoshop Dimensions are as follows:
2667 Width
16270 Height
Document size (points)
1280.2 Width
7809.6 Height
Resolution is 150 pixels.

After Effects Composition settings are:
Preset: DVCPro HD 720 23.976
960 Width
720 Height
Pixel Aspect Ratio: HDV 1080/DVCPro HD 720 (1.33)


Thanks to all,
