This was prompted when I did some testing after responding in this thread - https://forum.cyberlink.com/forum/posts/list/43151.page
Bottom line: When you add a background to a menu, whether you're modifying an existing template or building it from "Create Menu", whatever the resolution & format of the original image, it is stored in the menu folder as a 1920x1080 .png file.
You can mess up an image doing this, even with decent image editing software!
So what? Well - it's irrelevant if you started with a 1920x1080 .png image... but it's NOT irrelevant if you added (say) a low-res 540x304. That image would be upscaled (who knows how well?) by PDR in the menu making process, downscaled (who knows how well?) when burnt to DVD, then later upscaled again (who knows how well?) when played on a HD/UHD TV.
Then there's the image format... say you start with a fairly highly compressed JPEG. PDR converts it to .PNG (who knows how well?). The potential for blurry menu images is compounded if you start with a low res JPEG.
Who cares? I rarely burn disks myself, but if an editor had spent time shooting HQ clips, carefully assembling the project and burning it to DVD - why would they want a potentially fuzzy image front and centre of their production?
As Julius Sumner Miller used to say, "Why is is so?"
