    Hello guys..... Just a real quick question... I have a Bose 321 system. I have had it now for about three years, but never really used it to its full potential util a few weeks ago. I upgraded all the cable and now I am running opt cabling instead of composite audio...Now that I am using optical audio out from my 510 to my bose it takes the audio about 5 to 10 seconds to kick in on the bose unit. I have the 510 set for both PCM and and DD. I am more curious as to why there is a lag in the audio catching up to the video... Is it an issue with the audio being bufferd in the hard drive or is it an compatibality issue with my bose unit and 510..... Any help would be great... CC

    'composite audio"

    There is no such thing as composite audio... perhaps you're thinking analog audio?

    Anyways, I don't really understand your problem?

    Is there an audio/video sync delay; or is it just a delay for the receiver to detect the audio (the latter pretty typical, but not ten seconds!)?

    LOL Sorry it has been a long day and the brain is in shut down mode... :) It was the latter part of your answer that I was wanting to know about... I was thinking analog audio. I had never used the optical audio settings before so I did not realize there was a delay. The delay in the audio sometimes is as long as ten seconds. once it kicks in things are fine I was just more concerned that there was a deeper problem. Thanks for the answer... CC

    The problem likely lies in the 321 being slow to determine what type of digital stream (PCM, DD, dts) it is receiving. My old outboard processor took longer to decode PCM than DD but even then it was less than 5 seconds. The newer digital surround receiver I got to replace my hobbled together on-its-last-legs setup has no delay from any format. Sound decoding is immediate from a 501 (40GB version of the 510) and 921 (after the L211 software fix).

    My Panasonic does take a few seconds to detect the stream it's getting. My guess is that you're seeing a combination of delays (the sat receiver and the stereo receiver)
