I'm wondering if there is a way to tell an imported image to stay at it's native resolution or perhaps tell DVD-A the exact deminsion of the image rather than using the mouse to just drag it around.
I'm not sure I understand your question, but I'll try to help! I think DVD-A standardizes output, so I don't think you can keep it at the same resolution. You haven't said what you are going to do with the final images. If you are just trying to make a background image, you might try resizing in an image editor (Photoshop, etc). Even if you could render it at "native" resolution, you run the risk of the image being too large or small to fit the television screen. If you can be a little more specific about what you want to do, I might have a better answer for you.
In what program did you create the images. Do they use the full pixel amout (are they rectangular?) or do they have some transparancy in them? Just curious.
