    lol.
    Unless your friend has an engineer's cell phone number... He didnt actually talk to an engineer. If he called any of the DTV numbers (531-5000, 347-3288, 695-9251, etc etc), he got a CSR.

    EDIT
    removed single quotes from the word friend, as I didnt mean to put them there in the first place.

    OK, I have been with DirecTV for just a month or so, so I don't have a history of when I saw the problem vs. not seeing it. I just know it's there.

    Yeah, I don't know that I believe his friend really spoke to an engineer, but that doesn't invalidate the explanation. He's come the closest to on this particular thread to showing the real issue, though. Separate audio and data streams, and no real standard for syncing in existence.

    The Engineer is weaving you a colorful tale so you'll stop complaining.

    1) I use stereo output and I have the same Lip Sync issues

    2) I can switch to the Source HD signal for some of the same channels Via CBand and it has no Lip Sync problems while the DIRECTV rebroadcast has problems.

    3) I don't have problems on Mpeg2 HD channels only Mpeg4 HD and I have tried Mpeg4 HD feeds on FTA and they work fine.

    There are some problems with HD broadcasts but most of the problems that you find on Directv are only found on directv

    Ditto .... My experience has been only the MPEG4 channels get this problem (lip sync) - as well as the Audio Dropouts; hence why I didn't see this going on before the swap out of my HR10-250 for the HR20 & H20.

    Does anyone know if CNNHD is MPEG4 ???

    Then that makes total sense... 'Cause all of my Audio Dropouts & Lip Sync issues have been with the MPEG4 technology implemented. When I switch to OTA or SD, I NEVER see these 2 issues.

    I'm just repeating what was told.........I personally don't have any lip sync issues with my HR20 going through a receiver or otherwise.

    I watched CSI NY last night through my HR20 and receiver with no lip sync problem. All I got was a couple dropouts in the audio towards the end of the show.

    What's the deal here folks?

    Why are some here seeing huge problems with everything.....others with some channels........others with just the MPEG4's.......others say the MPEG4s are fine........this doesn't make sense at all to me.

    No. He asked too talk to a technical person, not a CSR.

    I still like cawgijoe's contact. It confirms the obvious, the DirecTV is getting beat up over the lip sync problem and that there is no easy fix. Given the paucity of information from DirecTV on this, knowing those two things for certain is news.

    BTW, I deleted a post upthread where I compared the output of my HR20 in the Dolby Digital and PCM modes. I realized later my test was bogus. Oops.

    In fact, that's the one line that reads really false in the "engineer's" info - that if you don't use Dolby Digital, you won't have the problem. I'm glad dreadlk has said he gets lip sync issues using stereo out (Sorry for you, dreadlk, but good for us. :D ). It's the same digital stream out, PCM or 5.1. Those two should be locked together.

    Why is it that my friend's system has no lipsync issue going from the HR21 directly into the TV?

    Yet the lipsync issue is there while decoding Dolby Digital through his receiver?

    Should not there be problems both ways?

    I will check this out in the morning since I've got the day off and we are installing a Winegard UHF antenna at his house.

    FWIW - my DD is turned OFF on my H20 .... so anything suggested that this is a DD issue seems improbable to me... but again, I'm no technician. Also, my HDMI cable goes directly from the H20 to the TV. No amplifier in between.

    Although I agree he may not have talked to an engineer, don't be too quick to poo-poo him. I have experimented using the voice prompts that Directv has and you would be surprized what departments you can get just by saying them. It is quite possible he could have reach a tier 2 tech (they consider themselves engineering techs) I have done it.:lol:

    My friend's connection is HDMI from the HR21 to the TV and Toslink from the HR21 to the receiver......DD turned on.

    No lipsync on the TV's internal speakers......lipsync via the receiver.

    YES!.....that's it! He told me he had reached a "tier 2 tech or engineer".

    Thank you!:)

    Gotta run for now guys......this whole thing is just bizarre.

    I don't know.

    Try this out tomorrow. Play the audio through his home theater system as straight and bypassed as you can. In other words, leave it in the loop but turn off all of the audio processing. I want two channel straight audio. See if that makes a difference and let us know.

    A receiver now-a-days has buffers built into it, certainly audio and maybe video. My Yamaha can step everything up to 1080p. There's bound to be a buffer to do that job. Plus there are audio delays built into Dolby Digital. Those steps in the receiver's menu about setting how far the speakers are away from you? You are setting delay times (1 foot = 1 millisecond). That's a buffer. Finally, a lot of HT receivers have audio modes to make your room sound bigger. If your buddy has one of those engaged, that's more delay.

    Check and see if his audio follows or precedes his video. That will tell us a lot.

    God, life was easier when I was into high-end audio and television was a Sony coffee table sized projector shooting onto a 50" curved screen. Give me a properly set up turntable and a straight wire with gain anytime. :grin:

    I was watching the PGA on VSGFHD and the sync was terrible. Either that or the microphones were a quarter mile away from the golfers which would explain why I was seeing the swing long before I heard it.

    It's time for all of us to start emailing DirectTV ... we need to turn up the heat IMHO. Maybe if we each get a reply back that they're "aware of the problem and are working on it" we can possibly assist them in trouble shooting this.

    Turned Dolby Digital off on the HR20, switched channels and then back to TWC-HD and the sync is "almost" on. Turned Dolby back on, and again switched channels and back, and its still almost on. Obviously much better than the 1/4 second it was off last night.

    As far as HDMI vs Toslink, I have both hooked up simultaneously. The audio through my 5.1 system (toslink) and TV (HDMI) are both in perfect harmony.
