Never occurred to me either about the power up sequence. I currently do tv, 990, cable. But I will try this.
Could there be a setting issue within my dvd or tv that could be causing this also. Should i reset the delays back to zero from what auto setup provided.

Skyblazer, how you been. I guess you can see that I bought the 7500 instead of staying w/NAD. I have done the auto setup several times and it has not fixed it.

A good way to troubleshoot the delay is to also hook up the component and digital signals to your TV directly from the cable box, assuming your TV has the ability to have a digital optical or coax input. As this removes the 990 from the mix, you can determine if the cable box is causing a delay with the video to the TV first and foremost.

Absent the ability to hook up directly to the TV both digital sources, then you should trial and error the coax versus optical on the 990 and see if this helps fix.

I for one tried the auto set up of the 990, but opted to manually adjust the settings myself instead. This was just related to speaker levels and distances. I did not adjust for any lip synch delay to any of the inputs. While the auto setup was close, I had to tweak a few things slighly due to my room layout not being uniform.

As I said, my lip synch issues were intermittent and only on the cable box, so rather than adjust the 990 for delays, I tried to reduce the occurrence of the intermittence and so far have been fine of late.

I am surprised at the suggestion that digital signals sent via coaxial and optical digital connections from a source unit to a DAC (the 990's or anybody's) could result in differences in audio lag over any length of cable less than ten thousand miles or so. Has anyone actual evidence or experience that this is so?

Just provides one less source of signal conversion by going with cable vs optical. I think you may just want to try the recommendation on changing your speaker distance settings.

My suggestion was not related to cables causing the delay, but more so that the codecs on the transmit and receive end for the coax and optical are different silicon/hardware within the units, typically shared silicon on the same IC, but also a different functional block within the audio codecs if they are hardware implementations in silicon. Hence, they could present the issue for the synch with the digital video stream depending on their implementations in hardware. There could also be an implementation where they are software codecs that runs on a DSP which can still present a problem.

Lip sync issues are totally the fault of the broadcasters. The reason for the sync issue is that audio signals pass through the various DSP stages in the broadcast station faster than the video signals, since video is much more math-intensive to process than audio.

Unfortunately it is left up to the home user to set "compensating" delays for the audio in order to get things back into sync. This sucks, but it is just a fact of life.

You can try to call and complain to the originating station, but I wouldn't bet on much action.

Not meaning to detract from all the great sharing of communication, but I was hoping to get more "out of the box" suggestive ideas on how to address the audio lagging behind the video. This is mainly on DVD. Thanks again.

If by 4 of every 5 movies on DVD, then you should probably fix this by adjusting the lip synch delay for the assigned DVD input on the 990. That is, if the delay is consistently always the same delay. Which Pioneer DVD player do you have?

On the player, you can also try to change the settings for the output, ie dobly digital or PCM stream. You also want to make sure that if you have a DVD Audio/SACD DVD Pioneer, that you don't set the speaker distances and sizes here and also on the 990. I only use my 990 for speaker settings and the Pioneer settings are off/full range.

It is the DV 563-A. I have the delay for the dvd input set to 0 on the 990. Moving up the scale will only make the audio lag more. I will double check the output and get back.
