Yes...I did not detect any changes in the sync problems.

too busy working on BluRay features i guess...

Audio sync and no WMV/Windows 7 support --->

I really don't feel like buying more blank DVDs... Oh well...

[Toonces T. Cat]

Yep...

Has anyone test any of the newer versions? 6.0.7.0 or later? Is this still an issue? Nothing official in the fix list from the looks of things... I haven't had a chance to test it out yet... Just wondering if anyone else did...

Thanks...

The only one of the mentioned movies I have in my collection is The 13th Warrior. I dug it out and give it a try using avi.divx.audiocopy. Something odd about the movie though it took a while to scan and was going to take over 30 minutes to make a VOB passthrough. So I did the avi from the disk and the A/V sync is spot on using 6.1.0.2 no problem at all. Looks like they protected it well!

I have at least three titles that this method does not work on...

Are these in addition to the 4 that you listed earlier in this thread? If not, maybe you should list them out for Ting...


Ting - Any progress on this one?

Thanks in advance!

Works on some DVDs...

I got it.. Had the same problem too. I found that adjusting the frames per second from 28fps down to 20fps syncronizes my audio/video perfectly. I notice it syncs automatically after about every 5secs of play. But adjusting the fps till u get it right is a success !!

I have at least three titles that this method does not work on...One of my first steps was to vary the frame rates and, sadly, on some DVDs it does not correct the sync problem. I tried everything from 15 to 30 frames and they would not sync up. For my device, a Samsung A867, 23.975fps seems to work the best. All of the other rates just make it worse.

Same here.

That was my point...

I encoded "The Emperor's New Groove" for my wife using DVDFab the other day and had sync issues. It was a split second off and got worse as the video progressed. I encoded the same disc with Handbrake and the encode went off without a hitch. No sync issues. I wonder what Handbrake does different to counter this sync issue.

That was my point in posting the info. I looked in the HandBrake forums also and most of the problems seem to be AVI related...I rarely ever work with an AVI that doesn't want to get out of sync...

Every DVD, and DVD image, however, that I've thrown at HB syncs up perfectly. I thought ting might find a clue in the source code...which is fully downloadable at the link I provided.

I would just much prefer to be able to do everything with Fab...

Some additional information. I created a disc image to speed the encoding process so both programs used the same disc image. The encode was done on a HP laptop with a 2.0 Ghz Core 2 Duo processor and 4 gigs of RAM. Regular compliment of background processes. DVD is a region 1 (US) disc.

Look forward to the next version of DVD to Mobile as I know Ting will figure this one out.

Handbrake may work in this case but is not a universal cure. I have seen many posts from its users about sync issues. Some audio problems have been corrected with the 6.0.7.0 release, try that.

This may be of help...

ting,

For what it's worth, I've found an open source program that seems to have overcome all of the problems with all of the "special case" DVD titles. As it is open source, I can't imagine there would be any problem if you took a look at it. Here's the link:

http://handbrake.fr/downloads.php

I'm doing the conversions using a Fab rip of the original DVD saved to the HDD. I created my own profile for my Samsung phone using the h264 and AAC codecs to create an MP4 output file...It's very similar to the Fab Profile editor, but you just set things up in the GUI and then "add" a new preset and it shows up in the list.

The only problem I've found is that it has no volume control, but I'm just bumping the aac track with MP3Gain + ACCGain and it seems to work fine.

The main thing about the HandBrake program is that it correctly recognizes the time info on the DVD rip and then maintains perfect audio/video sync throughout the file...Whatever they're doing has completely whipped the A/V sync problem I've been having.

I hope this is helpful to to you!

Here are the problem children...

hi,

sorry for reply this thread so late, I know current sync logic still have some problem for some special DVD.

if some source cause sync problem, please bold it in your post, so I can find it more easyable, like this R1: That Was Then...This Is Now,

I will try to find this disk and test it.

thanks

ting,

Here are the problem titles I've encountered:

1. Aliens: SE R1 (This is the extended cut from the Alien Quadrilogy set.) It is a "threaded disc" as it contains both the theatrical cut and the extended director's cut.

2. The 13th Warrior R1 (This is the only R1 edition still in print.) It is a multi-angle title as it contains two cuts of the films: one with English credits and another with French credits.

3. Streets of Fire R1 (This is the only R1 edition still in print.) This is a straight-up DVD5 title with nothing special about it.

4. That was Then...This is Now R1 (Unfortunately, this is now out of print.) This is also a straight-up DVD5 title with nothing special about it.

I hope this is of some help to you!
