I have two major problems with it:
1. The keyboard layout doesn't fit with any of the languages that I can choose in the TV's keyboard menu.
2. The touchpad part of the keyboard behaves itself very badly - practically I cannot use it. It seems as it was electrostatically messed up. The touch pad of the TV's remote works fine, so I think the problem is not my electristatic condition

Any idea how could I solve any of these?
