Cant rearange reorder icons

i have the AppleTV 3 with 1080p.

it has got the 5.1.1 (5433)

i have got weird problems.

1. when i want the appletv to standby, i have to "press and hold" PLAY/PAUSE only in the first row of the homescreen. other people "press and hold" on Select. why?

2. when i want to "press and hold" the Select button on the other icons like WSJ, it acts like i have selected it. ive tried it 1000x.

when i "press and hold" the play pause button it makes a small beep and nothing happens.

who can seriously help? ive plugged the appletv out too, but it didnt help.

fyi: ive installed the new os 5.1.1 2 weeks ago over ethernet. had no problems with that.
