Try turning off the Dolby digital audio when using the Toslink. Dolby
can add about 0.5 seconds delay. DTS audio might have less of a delay
and is worth trying. Toslink does NOT have a lip sync specification
because there is no associated video channel. That might explain why
Panasonic isn't very responsive to the problem. If you want tolerable
(not perfect) lip sync, HDMI 1.3 and 1.4 are the only interfaces with
a functional spec.

I never thought about this before.

Does that mean that any old surround sound-ish system could in theory have
audio horribly lagged and off from the video from the source such a DVD?

I've noticed there are delay settings on most audio decodes but, I've not
noticed or though about there being sync issues with the audio as a whole.

MiniDV was another story, and a complete waste of my time when I used it.
