Phil:
Who said anything about the cable putting things out of sync? From WGD's info, it talks about processing time. At least, that's how I interpreted it in this particular message. Kevin On Jul 12, 8:36 am, wrote: On Wed, 11 Jul 2007 23:23:32 GMT WGD wrote: | Lip Sync: Because consumer electronics devices are using increasingly | complex digital signal processing to enhance the clarity and detail of the | content, synchronization of video and audio in user devices has become a | greater challenge and could potentially require complex end-user | adjustments.

It's not the cable that gets things out of sync. It is the processing circuitry itself. If that circuitry were to ensure that audio and video were tagged together, this would not be a problem. Putting time tags on the audio and video in the transport protocol coming over the wire might be a convenience to such circuitry, but it is by no means necessary since that circuitry could apply any arbitrary sequencing of numbers itself. All that is necessary is that at every step any equipment puts out audio and video together, it must put them out already in sync. It's not the cable that can bring them back in sync. The cable cannot do that. The interface to the cable might, but that is absolutely the wrong place to put it. This is nothing more than an attempt to shake down consumers for even more cash by forcing them to buy something even newer that very likely gains them nothing at all (just fix the broken circuitry that is getting things out of sync). -- |---------------------------------------/----------------------------------*| | Phil Howard KA9WGN (ka9wgn.ham.org) / Do not send to the address below | | first name lower case at ipal.net / | |------------------------------------/-------------------------------------*| |

Thanks. I actually just ordered the silver version. Some reviews
said that the conversion to 720p isn't so hot. Some reviews also said that that receiver downgrades 1080i component connection to 720p. Options in that case are to disable the DCDi circuitry or run HDMI directly from the source to the TV (for the video). And thanks in part to these discussions in this thread, I know more about how to handle the audio. Thanks. Kevin On Jul 11, 5:53 pm, "go_dawgs" wrote: "k-man" wrote in message ups.com...

I have the Onkyo SR605 and a Panny Plasma. For HDMI inputs the SR605 will directly pass the video signals with no processing. The SR605 only applies video processing on analog inputs to allow 720p on the HDMI output. You will also need to send the TVs audio back to the SR605 for over the air programming (optical or analog). The SR605 has worked flawlessly so far, and has excellent sound.- Hide quoted text - - Show quoted text - |

Anyhow, anybody have any insight, anybody dealt with a similar scenario? The Oppo 981 has optical and coaxial digital audio outputs. Most AV receivers now have more than one optical input. Some TVs don't pass through digital audio from their HDMI inputs to their optical digital output. Mine doesn't, so I use a separate path for digital audio to my receiver. I've never noticed any audio sync problems with DVDs on my Oppo 981, only with some digital OTA broadcasts. Thanks. That's good info for me. Thank you. Kevin |

Hi Phil:
I still don't understand. I don't know anything about a cable being fixed. Maybe I missed someone's post; but all I recall about a cable is that someone said to not buy an expensive HDMI cable, which was sort an "aside" comment.

The Onkyo SR605 is a receiver/amp, not a DVD player.
