Sony s-300 and U-control (universal movies)

[peterfabian]

Hi guys, i bought my 2 first Universal Movies and they come with a special feature: "U-control". The icon appears on my screen but it doesn't seem to work on my S-300 (for example picture in picture feature). I press the center button of the remote but nothing it happens. Is really not compatible S-300 with this feature or i have to press some special button for the function works? Thanks for your help.
