Audio out of sync on 5.1

[jjc]

I've encoded "Are we there yet?" with windows gui 9.2 using the apple tv preset without any other changes which results in the movie being played in 5.1 through my receiver. There is an audio delay of about 2 to 3 seconds on the apple tv, but when I watch it with quicktime there are no sync problems. I've encoded plenty of other movies, including this one, with prior handbrake's window versions and have never had synch problems. By the way, I use an ethernet cable to connect my apple tv to my computer. Any tboughts on how to remedy this problem?

Is this your first 5.1 encode? Have you tried any other films or TV shows? The time delay could be due to your HT setup (time needed to decode the surround digital signal), and not HB's problem.

This is my first 5.1 encode. However, I did encode one chapter as a test and the 5.1 audio is in sync. What is the HT Setup?

Do you have your computer hooked up to support 5.1? If not then then audio playing out of quicktime is probably in sync because it is playing the stereo track instead of the 5.1 (I'm assuming you're using the AAC + AC3 setting so you have both audio tracks, which could be a big assumption).

A couple of discs have caused this for me (and it's been reported a couple of times in the problems discs thread), but running them through AnyDVD and then DVD2OX has always solved it for me so far (admittedly I'm only about 10 discs into my re-encode project thanks to 5.1 support).

Actually, I do not have my computer hooked to play 5.1, so that I guess is why I am not having any problems with quicktime. It was encoded with AAC plus AC3, which I believe is part of the apple tv preset. What is unusual in the current situation is that the one chapter that I encoded with the apple tv preset plays the 5.1 fine without any sync problems.

I found that the Dolby surround stream was in sync for me but the 5.1 was out of sync (Casino Royale). So if you play it on your PC you will likely use the Dolby surround stream (stereo) and so will look to be in sync but as soon as you play it via a 5.1 system it will use the alternative stream and look out of sync.

Regarding copying a single chapter it seems in my experience that that the issue occurs where there is the zero cell problem. From this point on the movie (5.1) is out of sync. So (I will test and confirm now) I suspect if you just encoded the chapter with no zero cells you won't have the issue. For example Casino Royale has the issue in the 1st chapter I believe. I will test it by encoding say the 3rd chapter only. My guess is both sound streams will be in sync. I will confirm....

I encoded chapter 3 and both streams were fine. Am encoding 2-28 to check this will be ok (thus leaving out the zero cell segment).

...chapters 2-28 worked fine (you miss the 1st 7mins of the movie).

Thanks - that probably explains it. For what its worth, I have encoded 3 additional movies in 5.1 and have not had any further sync problems.

I assume the guys that matter know about this and will address it in due course.

I assume the guys that matter know about this and will address it in due course.

As and when it occurs to us. at which point it will be fixed pronto

Just to back up everything you've said, I have experienced this as well with CR. Others have stated they have successfully ripped ZC movies but I've not had success. In addition to the audio sync issue mentioned here, the first 30-45 seconds of the movie "repeats" and jumps to parts of the chapter one scene. Eventually the movie starts over and plays normally, audio issues not withstanding.

This is on ATV 2 ripped via OS X w/ a number of different encode settings, including the stock ATV one.

Casino Royale is a known problem child. For source specific issues please consult this thread: http://forum.handbrake.fr/viewtopic.php?f=5&t=266

Keep in mind folks,that there is more than just Zero Cell Copy Protection with CR. Since there *seems* to be a lot of users having problems with this DVD, I will give it a shot tonight (while I wait for updates to my own issues).

[Abulia]

Oh, I know CR is a problem child. One person in that linked thread said they got it to rip successfully:

http://forum.handbrake.fr/viewtopic.php?p=26840#p26840

I wonder if it actually did rip successfully or just appeared to? (And I asked as well, in said thread, too.)

I moved on to other discs with the presumption (fingers crossed) that this would be addressed at a later date.

[Cavalicious]

A bunch of us got it to rip successfully....back then (pre-AC3). It's a new ball game now. I was able to rip the main title with Fairmount & DTOX (in Tiger). HB can now handle *some* Zero Cell DVDs when directly fed to HB. CR just came up because it one of many DVDs that were plagued (and popular).

9 times out of ten, I'm not going to be waisting time trying to circumvent protections. I'm going to use my AnyDVD workflow (yes, I'm on a Mac), sparse out the main feture with DTOX, remove the Zero Cells and encode /w AC3+DPLII. I just want to prove one way or another that its the "rip" that matters and not the encode.

[Cavalicious]

Now that I'm NOT going by memory...Casino Royale Doesn't Have Zero Cells!

...and here I am believing ya...

Actually, if it did, the new version of DTOX must automagicly ignores them, because they aren't showing up.

[EDIT]
PC: Fixed priority setting.
PC: Added manifest for XP controls.
PC burnengine: Added disk insert notification disabling and support for +R DL.
Mac: Fixed handling of burn -6 error.
Remember burnimage path for 'Burn DVD-image' menu option.
Remember drivename in case there are more than 1 writers.
Changed way empty cells are automatically removed from cell list in movie-only mode.
Added full disc scan for full disc mode. This might help when the output size is too big or too small.
Added Polish language (thanks to Maciej Bojakowski).
Removed hostname lookup from startup to avoid possible delay (thanks to Jim Hoyt for the tip!).

Casino Royale Doesn't Have Zero Cells!

It absolutely does, at least in R1.

Right, it does. The latest dtox doesnt show them as it ignores them automagically. You do not have to deselect them in the latest dtox.

Conclusion, its in the rip. My Casino Royale is in sync (both tracks).
