PSD menu cropped in Encore

Hello- newbie here,

I import a photoshop menu and after I create DVD in Encore, the Menu is cropped off on all 4 sides on monitor (checked on 3 monitors).

I've tried resizing in photoshop under image size. Encore 1.5 imports it the same size everytime- unless I use unconstrained proportions. This naturally upsets the balance.

The scale option in Encore DOES NOT work with my layered PSD file. I select all layers and as noted in the Encore Manual, by scaling any layer, ALL layers should adjust equally. Instead I get an error:

"sorry, an abnormal condition has been detected. Before quitting, u have one chancew to save your project"

Does anyone know how I can scale my layered PSD menu in Encore or what is the proper image size in photoshop (720 X 486 is Cropped in Encore).

I'm NTSC based.

Thanks.
