Redcrown,
PSG doesn't know a mask from picture. Generally what you need to do is to design graphics specifically for the aspect of your show. Your Gold "mask" is nothing more than a graphic with a hole cut in it. As such, you'll want to sit down and do the math. Then, create your frame (with the hole that the image will peek through) accordingly.
For instance, a 2:3 portrait set to Fill frame and sized to 30% zoom in a 16:9 show will be 80% of the screen tall and 30% of the screen wide (fill frame normalizes the image to the screen such that the image is sized to stop changing size as soon as the left and right sides are the same as the screens, you may have a small amount of image overflow to the top and bottom, with that amount getting smaller the closer your image gets to 16:9 (or a ratio of 1.778)). As such now, the horizontal is 1:1, percent-wise). In a 4:3 show, it's now 60% tall and 30% wide.
That means you have to design your "mask" graphic accordingly. That hole is going to change size with the change in show aspect (and scaling) no matter what scale you choose and it will only look correct in show aspect for which it was designed.
In Producer, you can create a gradient or solid layer that can act as a mask. You can set it to the aspect desired for your image display. Since both are relatively the same aspect (and same zoom setting), when you change show aspect, they will both change the same (both should be the same scale).
The way you determine your image size in a screen, at least for the fill frame scaling is W=Z, H=Z*F, where W is the layer width, Z is the zoom value and F is the Correction Factor. F is nothing more than a ratio of the screen to the layer. So, F = (Ly*Sx)/(Lx*Sy), where Lx is the layer's horizontal dimension, Ly is the layer's vertical dimension, and Sx and Sy is the shows horizontal and vertical dimension (as in 16 and 9 for 16:9 aspect show). It's the same as: (Sx/Sy)/(Lx/Ly).
Yes, math. But, it removes some of the questions about how to correctly design things for (for placement and/or size). Once you have a working frame of reference, designing your Gold frames is a bit easier. Now, you can work with your normalized percentages for designing the correctly sized hole, as well as their placement in the frame.
Hopefully that helps. You might want to check out my blog as you get more familiar with how ProShow does some of its stuff. Most of it is for Producer but some is appropriate for Gold (for calculating rotation center, for instance...).

PS pan is pan. .. that is 50% of the screen will always be 50% no matter what aspect your show is. So, I'm really not sure what you are telling us when you say that pan and zoom are aspect related. They are not.
However, there is a relationship that you might be interested in. Pan, zoom, and rotation center are related by the following relationship (for Fill Frame scaling): P=R*Z for the horizontal movement and P=R*Z*F, where P is the pan setting, R is the rotation center value, Z is the zoom setting, and F is the correction factor given above. Note that Z is a decimal number in these equations (as a number less than 1). If you use the value you seen in the zoom box then you need to divide Z by 100. So, a 30% zoom is 30/100 = 0.30. Why is this information important. 1) Now you know the relationship between functions. 2) You can calculate what you need to calculate with ease. 3) Only the calculations in the vertical are aspect related … and that's only when the layer's size is different than the show's aspect. Note, this holds ONLY for the scale of Fill Frame. The equations for Fit To Frame are similar, but there are different assumptions to consider. The same goes for Fit to Safe zone (it's a variation of Fit to Frame). Well, that should give you some fodder to work through.
