High Image Quality Using Photoshop Layered Menu

I have been creating DVD layered menues in photoshop then bringing them into to DVD Studio Pro as a layerd menu. The qulaity of my backgrounds and layered images for the menu seems to go down when I bring them into studio pro and burn a dvd. Does anyone have any suggestions or tricks to get higher quality from photoshop to studio pro. I have tried different things like deinterlacing to take away some of the jaggedness. That didn't seem to help. I duplicted layers then merged them to try and fill in but that did not help. How do I get my graphics (not text) to look sharper and cleaner as they do in photoshop then when I create the DVD in studio pro. Are there any filters I can get that will help with this Thanks
