Vegas DVD Architect is 7th version. I haven't try it as I'm still working in DVDA5.2, so I don't know any improvement of it.

As for the PSD import menu, in short, you need to follow these named-layers for DVDA to detect (Ref: help file) :

• button-01-thumbnail : A layer containing a thumbnail image for a menu or button. Can be abbreviated tmb.
• button-01-thumbnailmask : A layer containing a button's thumbnail mask. Can be abbreviated tmbmsk.
• button-01-highlight : A layer containing a highlight mask for a menu background or button. Can be abbreviated hlt.
• button-01-frame : A layer containing a button frame. Can be abbreviated frm.

A more detailed guide is available from the help file. Here's one page I have printed to PDF for you to read:

I also followed this help to create the menu and still use it until today.

For the following screenshot: I only use tmb and hlt

or for picture, just tmbmask and hltint:
