Wow, decorated for Christmas! Pretty! It would be great if I could do up the house with this kind of wallpaper.
But I just realized the remote for TV2 is exactly the same model, #148786, and works with a key that is blue with a 2 on it.
The one upstairs won't work through the wall whether it has the black key that says 'UHF' or the green one that has number 1.
Ventilation,
it's a big closet, not very stuffy, but how much ventilation should it have? (If it were up to me I'd leave it where it is, but it's not).
If people stick them in tv cabinets or entertainment centers, the closet in question is more ventilated than that.
