After accessing NetTV, I can see the NetTV startmenu only for a few milliseconds. Suddenly I get my original tv channel back, showed in 'picture in picture' mode (small screen upperright on tv screen). I cannot return to the menu anymore. After pressing 'back' I return to the tv channel instead of the NetTV startmenu. The problem has started yesterday (Dec 3rd 2010). I've already installed all firmware updates and turned the tv on-and-off for several times. I'm using a Philips 32PFL7605/H in the Netherlands. Is it a bug I can fix myself?
