I couldn't find a discussion thread on this subject, so if one already exists, please re-direct me.

I have had my new 65VT60 for about a month, and it has some pronounced but variable(?) lip synch issues, video lagging audio, and thought I would fly it past you experts. Here's my setup:

Cisco 8642HDC set top box HDMI Out to #2 HDMI In on TV, digital optical Out to Sony STR-DA1ES receiver
Panasonic DMP-BD655 blu-ray, HDMI Out to #1 HDMI In on TV, digital optical Out to Rx
Ethernet (Netflix) to TV, digital optical TV Out to Rx

The TV seems to be at least partially responsible for the delay. Here's what I have done to troubleshoot: I usually keep my TV muted because the HT sound is so much better, but when I do bring up the TV volume the audio is perfectly in synch from the TV and receiver from both blue ray and Netflix sources (the cable box has its own issues). HOWEVER when I notice the lip-synch problem I will bring up the TV volume and there is a distinct echo between TV and receiver. When I notice it on Netflix, the delay will be present on blu-ray as well. Sometimes both right on, sometimes video delay on both.

I know HDMI 1.3 is supposed to have an auto lip-synch feature, but I can't find it in even the advanced TV setup menus.

Help?

Why not use your Sony AVR as the heart of the system and connect everything through there? (I suspect this is why you're having lip-sync issues). Typically, your HD cable box's HDMI 'output would be connected to your AVR's CBL/Sat HDMI input. Blu-ray to your AVR's Blu-ray input, and your AVR's HDMI out to your Panasonic. Use the Sony AVR for switching sources (as its supposed to be).
If your Blu-ray player doesn't have an Ethernet input, I'd recommend replacing it with one that does - then the Blu-ray player is the source selection for Netflix, etc. Maintain surround sound that way too.

If the Sony has an HDMI 'pass-through' feature (where it will pass through the HDMI signal when the Sony is turned off), then you can use the TV's speakers for low volume/late night. Otherwise, use your HT system's speakers.

Bottom line is, I'd hook it all up differently - you'll get better sound from your HD cable box via HDMI than with optical anyway (and in surround, whereas optical is restricted to two channels...

having the same issues with st60. with cable its barely noticeable but with netflix its really bad at times and other times seems to match up a bit closer.

have my system hooked up to receiver through arc.

one hdmi going into hdmi2 on back of st60 and blu ray and cable box connected via hdmi from back of receiver into those 2 devices. pretty simple setup but lots of lip sync issues.

Thanks for the responses. To begin with, my Sony is well over five years old. It doesn't have HDMI inputs, let alone pass-thru. It worked wonderfully with my Pioneer 5070 all the way up to when I replaced it with the VT60. I will probably replace it with a newer receiver and use it as the heart of the system. However, I am suspect of the TV because, and ONLY because, the delays vary from watching to watching. One time it is right on, the next it lags.

I understand that HDMI 1.3 has an auto lip synch feature, and am hoping that when I purchase a new receiver it will communicate with the TV and make adjustments on a watching-by-watching basis to compensate. I don't know if that is asking too much, but I can hope.

However, it sounds from the second post that it might not happen.

Yes, a new receiver would probably go a longs ways toward helping you with this issue, (and solve several other connectivity issues at the same time!).
(Might be a Netflix issue as well?, as that seems to be the primary common denominator here...).

Im coming from a old samsung plasma about 3 years old and bought a new receiver when I got my st60 that has hdmi inputs and lip-sync feature.. old receiver and television didnt have either and worked fine. would think this set up would have a lot less issues. Sometimes watch netflix at my girlfriends house on a ****** old lcd and it works perfectly

I recently purchased a Oppo 105 blue ray player and the 60" VT60 and I also have lip sync issues,  The Oppo only has a -100 to +200 ms range, I have it maxed out at +200 and that isn't enough.  Oppo tech support suggest turning off some of the video enhancement aspects of the VT60 but I still can't see to correct the problem.  Looks like I will need a surround sound processor that has a larger range of adjustment.
