It's not the fetching of the images that's the problem; it's the box scaling the images that's so slow. What size are the images you're using for your posters?

Thanks JT. A quick look at a few of the images served up by the feeds looks like their size is in the 640x360 area. Not small but not huge either. I'm going to go through more of the channel feeds I'm using and see if there are any that are way too big. I'm guessing they're all in that medium sized range. I quess I was hoping there was a way to cache the "resized" images, but apparently not. Bummer. It would be a HUGE performance boost if the box would do that. I suggest that be closely looked at since I assume many developers don't have access to the images being served up.

I've been using the arced-landscape style which uses an HD image at 290x218. The arced-16x9 style uses 385x218. I wonder if that would help any? I'll try it and see.

Re: Slow posterScreen navigation

Have you tried using the different SetListDisplayMode options (scale-to-fill, scale-to-fit, zoom-to-fill, photo-fit) to see if the different scaling methods each one uses improves performance with the particular images you're using?

For what it's worth, the grid screen doesn't suffer from this problem, so if your channel is easily adaptable to a grid layout, that might be another option.
