Combines everything confirmed so far (trailer sound + zoom, Samsung TV Plus audio stop) with new fixes:
- Previous app (e.g. YouTube) visible behind the trailer — our main window is now marked opaque so the TV stops showing the old app underneath.
- Black screen / no sound after closing Nuvio — the player is released and the windows are hidden before the app exits.
- Tizen 9: app stops after the first frame when opened from the TV menu — new window setup for Tizen 8/9, plus the on-screen diagnostics from diag-tizen9-tpk.1.
- New: when a card trailer is playing and you press OK, the details page keeps the same trailer and turns the sound on.
Please check:
- YouTube → Nuvio → play a trailer: is YouTube still visible behind? Most important: do trailers and movies still show video?
- Close Nuvio: does the TV's own screen and sound come back?
- Tizen 9: open from the TV's app menu — does it keep working?
- Card trailer → OK: does the details page continue it with sound?
