I think its also, a bit interactive with your brand of choice STB. There is a delay (and I can surf bigtime so I see it all the time) but I've become used to it and never notice. When I brought home a new HD200 to try out, it was odd, the menu change and even partially the lock-on time for channels was lighting fast as compared to my old DTC100. I expected to see the visual up even longer before I heard my audio but did not. The 950 while still displaying a lag, did not extend its lag time as I expected after seeing the aquistion time speed up, so it appeared the faster Sony HD200 sent the audio signal to the 950 a hair faster also. It killed me to give up the menu speed increase and improvement in PQ and UI, but the thing kept freezing up on me so I'm back to the DTC100 trying to be patient, looking forward to the next batch of HDSTB's to give a demo.
