Hi Gonk,

1) yes I till get audio but lose the picture. The only way to get the picture back is to turn off the 990 and turn it back on to the video source. Yes this is throught the DVI out.

2) yes it happens when the TV program is switching formats but also when ever I switch sources it also happens. It comes from all my speakers....

I cant believe there is not an explanation....I am using the balanced connections on my amp.

I do love the sound but am very annoyed with the popping sound....
