It would be nice if Roku was smart enough to only deploy the local FHD resources to devices that can use them. It would be a good way to keep the file size down for the Roku 1 players.
We've noticed that JPEGs look pretty bad as a splash screen - lots of weird artifacting that I don't see on my computer.
Thanks for the response. To be fair I had not tested it on a Roku 1, but when I install the application on my usual Roku3 development device, I get:
"Warning: Application size prevents it from working on Roku 1 players (3471281 > 2097152)."
PNG - looks great!
JPG - look closely at the screen and you'll see an artifacted black grid slightly offset from the white grid
Would love to know if you see it too.
