Sony Receiver Audio Delay Question

Hi, I am looking at a Sony Receiver STR-DE898. In the description it

A/V Sync: The audio output can be delayed so that the time gap between
the audio output and the visual display is minimized. This is
especially helpful when you are using a large LCD or plasma TV or a
projection TV. Note: A/V Sync cannot be used when the Multi Channel
input or Analog Direct function is used.

What does the "Note" mean? I can't figure it out.

Arny Krueger...

I have a friend with a new 61" Samsung DLP HDTV who decodes
Dolby Digital sound tracks off of Comcast cable. Looks
great!

I can't remember the precise details, but he ended up with a
ca.200 mSec delay between the picture and sound with the
sound leading. It seem like the HDMI interface played a role
in the problem. He ended up buying a $200 consumer audio
delay line that is popular for the purpose.

Richard Crowley...

It means that the delay function works on only some
of the sources and not for others.

My assumption is that it works with the digital inputs
(because it is relatively easy to delay a digital signal)
but not for the analog inputs (because it doesn't do A\D
conversion).

Thank you for any help.
