Still Menu Shaking on DVD-R

[Deepa DvD]

Heyy sup everyone!
I have another problem. ...problems these days.:(
I created a still menu in Photoshop 720X480 (for NTSC).When I burned it onto dvd-r.I played it on my set-top, it sort of shakes a little, where the buttons are.I authored it with ScenaristNT.I didn't burn my whole scenario, only part of it, because this is a dual layer project.And the type of file types I imported into Scenarist were Photoshop .psd files for both the still menu and the forced subs.
Does it have to do with some field order or sometin?
I'd appreciate your help!:)

soften your images a bit (blur, 0.2 f.e., you won't see the difference). It is related to interlacing...

Thanks bro!!:) How do I do that in Photoshop?

And also I forgot to mention, the shaking is on the text that is the highlighted text. The text was created with Photoshop.

I have had this problem too with subtitles. With the 'shaking' menu's, blurring (filters => blur => gaussian blur) did the trick. However, with ripped subtitles, there are too many to blur them, and i don't think blurring subtitles would be smart (they have to consist of 4 basic colours, blurring would create some 'intermediate' colours i think).
