I have had the same problems, I started with archers file as a base and took his bitmap (from MainB on home which look great) into photoshop elements 2.0 and changed VHS to SVHS and put my device name below. Paste one in and it works, pasted in a second different one and it shows fine in the import bitmap window, but when it appears on the layout, it looks like the one I removed...
I have since pasted these and others all at the same time into the default file and they work there.
