Following from my earlier comments on the other thread, I have also noticed the following having run the 434 for over a week: On at least 3 occasions I noticed that the picture signal will disappear for 2-3 seconds and then return. It happened during normal viewing of digital terrestrial TV or analog TV. I do not think I have seen this yet through DVD or digital satellite. When it happens the sound remains, only the video signal disappears. It looks like the media box is re-processing the signal (signal drop?) for a second. Furthermore, and in addition to the slow response me and others have mentioned when you change inputs, occasionally the new input signal will appear, go off and re-appear before it settles on my screen. Have any other 434 owners notice this?
