I see.. yeah that sounds like an issue. If these devices are virtual (added by the app instead of the Hub) then the hide option isn't there. I'll have to think about this.. it's certainly possible to fix though so I'll figure something out.
In the meantime, just something I've done with all of my camera feeds is to create them on the Hub. I did that so every client will have the same tiles and they don't have to be re-created on the device.. also just easier than typing a URL on a phone. I use this Hubitat driver to create images/video tiles. This one works too.
Another workaround might be to put the original video devices in a folder. That way you can still access them but they're not being displayed at the same time
Somewhat related to the media selector tile I made some changes to it as well in the next version..
- Fit (no crop) option - determines if the image/video should be cropped to fit the entire tile or not. It was there previously but hard to change
- Allow ordering devices
- when full screen, show same actions as a normal image/video tile
- image -> refresh (if this image can be updated)
- video -> mute/screenshot/record
