It appears that shortcuts (pointing to movie files) aren't seen as videos.
I organized my movie + TV show collection by genre/etc. using shortcuts, and was sad to see that it's not working, at least over AirScreen.
AirScreen should follow these shortcuts, allowing users to easily watch something without scrolling through a ton of files! 😄
