Got a question for you other denon 4308 owners!
I recently purshased this unit in my local second hand market as an upgrade to my current denon 3312. I have pretty low impedence speakers and the 4308 certainly sounded much better than the 3312. The center channel really opened up and I was delited with this buy.
However, I soon discovered this odd thing. You see, I have 2 sources, one digital tv box and the mediaplayer Boxee box. Both have worked great connected through HDMI to the 3312. But sadly, through the 4308, specifically with boxee, there is now quite often a lipsync problem with many movies. This can ofcourse be adjusted using the audio delay option, but it is quite boring and time consuming to do so. In addition, the amount of "adjustment" needed is different from movie to movie.
If I switch back to my denon 3312 and connect the boxee box (again using only HDMI cable) the lipsync issues totally dissapear. Everything is perfect. The setup is the same in all other aspects.
Obviosly, the more modern denon 3312 is doing something to the HDMI-signal which makes it have perfect sync. However, this is somehow lacking on the denon 4308 despite having turned on "auto lipsync" option inside its menus.
I have installed the latest firmware. Also turned off all sorts of scaling of the picture but still problems. With my digital tv box there is much less pronounced, but still got this feeling that lipsync is just slighly off (1-3 ms perhaps). Adjusting it is difficult since I dont seem to get in perfect sync (its like it is 2.38 ms or something). Reinstalling the 3312 and this feeling totally dissapear, voices are just spot on.
Is this a known issue with the denon 4308? Perhaps it has something to do with my TV (sony nx720) not properlly communicating the audio delay needed to the 4308? Are there any other Boxee box owners here with a similar eperience?
Anyway, any input would be appreciated.
