2910 - picture/sound sync problem

[burgor57]

Anyone got any idea about this problem?
I just took delivery and set up my new Denon 2910 and Paioneer PDP-426SXE.

At first look everything is wonderful - very impressed. Then last night I sampled a look at my DVD of Steely Dan in concert 'Two Against Nature', expecting to be joyfully entertained. However, there is a serious picture/sound sync problem with this disc, not seen on watching movies.

The 2910 is outputting the signal as progressing 720p via HDMI.

Anyone got any ideas whats up?

If it happens on just that disc then it could well be a mastering problem. Some discs do suffer from lip-sync errors. If your Amp has a master audio delay setting you can cure it that way. Any chance you can test the disc on another player to see what happens??

Alternatively, try different resolutions from the player and see if the same happens.

I have watched this DVD many time on my previous budget DVD player with no problems at all.

Strange it's not apparent on other discs though. Try another resolution and see if the problem still exists.

Well I tried that last night with no joy. I'll try again this eveing. Funny thing is I thought I noticed it on playing the Eagles DVD too, but it was only at the begining and it was only slight so I ignored it.

Wonder if anyone else has had this problem? Is it a settings issue on the Denon 2910, or a wrong setting on thew Pionerer PDP-436SXE that conflicts with this DVD? Or is there a ppossible problem with the new 2910?

I have a Pioneer 436SXE too and a Denon 1920 and it always showed lipsync problems with most of my DVDs. I cured the problem with the AUDIO DELAY feature on my receiver (Denon 2807).

Well that surprises me. I'm a little sorry to hear this. My cheapo DVD player never gave me these problems. I'll have to check my AV-amp to see if it has a sync delay function (never looked for it before). Is this likely to need setting to different values for different discs? Is this a common problem I've just never heard of before?

Anyone out there got the same setup as me, and by chance got the same Steely Dan DVD? Would love to hear if you get the same problem. And has anyone got an explanation for it?

Video Scaling/Processing can introduce lip-sync problems but it can also be down to duff mastering (some DTS tracks are known to have lip-sync errors). Some players automatically adjust for this but you can't really correct a disc that has an error to start with. An Amp with audio delay can help to some extent but you may find the sync varies throughout the film so you'll be there adjusting it every five minutes.

[burgor57]

Noooo. Don't tell me all this. This is not good to hear. I played this DVD many times on my budget DVD player and it never gave me lip sync problems, even playing the DTS audio. And to be fair it was not at all bad sound and picture for a budget DVD player - it took some persuading to get my other half it was worth 'upgrading'. And who want's to be fiddling with sync settings all the time. Come on - someone tell me they have a Denon 2910 and don't have this problem!

[Jase]

We've got a 2910 as well and don't see any lip-sync problems (connected to a Panasonic AE900 PJ via HDMI). I don't have the Steely Dan disc to test out though.

I have a denon 2910 not to your particular screen but I have never had any lipsync issues with it on any disc I own (and I own many)

[Crustyloafer]

Switch off the scaling on the player, it will be creating a delay as well as the screen's own processing. These two delays combined make it very noticeable. A budget player like the Denon 2910 should not be relied upon to have high qulaity scaling, it is best left turned off.

[burgor57]

Didn't think of the Denon 2910 as a 'budget player'. And one reason I baught it was for the upscaling which I understood was quite good. So are you suggesting I leave the upscaling to the Pioneer PDP-436SXE? It would make sense to only have upscaling processing done once that fair enough. To be honest I didn't realise the plasma TV was doing any upscaling. Are you confident that I should let the Pioneer plasma do the upscaling then?

Just try it. The decision is reversible!

I have had this issue myself on occasion and put it down to the 2910's well know fussy nature with certain DVDs especially copied disks and dvd-Rw's. I have to say that i've been ok with 99% of normal movie dvds though.

Whilst the feature of time delay in this years denon amps sounds good on paper, this is surely only useful if the issue is constant and consistent.

The upscaling feature of the unit is probably the reason you bought it (it was for me), but it does seem that this can introduction problems very occasionally. the one i particularly remember was the latest special edition of "a fistful of dollars". I began to wonder if it was actually dubbed...
