I updated my 7605H/12 TV to the latest firmware version of december 2011:

Version:, ZIP-Datei, 70.87 MB, Veröffentlichungsdatum: 2011-12-12

looking TV works OK, but if I start the TVGuide, I am no more able to move the cursor using the TV remote! I can't select another channel to read the TV program. Also if I enter NetTV mode, it is not possible to move the cursor or select a NetTV channel. Can you please look into this issue and solve the firmware bug?
