DVD-9 to DVD-5 audio sync goes bad later in the movie

[zilber]

I followed these instructions, and the video turned out great, but throughout the movie, the audio became a little late. I used the quicktime export to MPG2 codec to step down to 5200 bits. Could someone please post why this would happen, and what should I do? I still want to keep the 5.1 surround. Everything works well as long as the movie is < 4.7 Gb. Anyway, here are the instructions that I followed:

Software Required:

OSex

DVD Studio Pro

Quicktime Pro with mpeg-2 decoding component

MissingMpegTools (you need to update mplex inside for this to work)

--you can get the most recent mplex out of ffmpegx (control click- show package contents, go into contents/resource folder and COPY mplex out onto your desktop or somewhere similiar, control click on MissingMpegTools - show package contents and then go into contents/resource folder and delete the mplex in there and replace it with the one from your desktop.. or wherever you copied it to)

Toast Titanium (you can go without toast, but i prefer burning in there rather than DVD Studio Pro)

1. Insert your DVD and open OSEx
2. Make sure to deselect all audio streams except the first one
3. Make sure to deselect all of the subpicture streams as well
4. press the FMT button and select elem. streams
5. press begin and select an output destination and wait for the blue bar to finish.
6. multiplex the m2v and the ac3 stream in missingmpegtools - choose force segment to 4000 MB segments (if applicable) mmt will launch the terminal and the window will remain motionless while remuxing the streams, (there will just be a big blank space, just wait till its done) if all goes well the terminal will say INFO: MUX STATUS: no under-runs detected.

7. open one of the files in quicktime and see what the size is under more info (quicktime interprets files differently than our other applications, when mpgtx reports it as 720x480 sometimes quicktime will say its 640x480)

8. make a blank graphic that is the size you determined in the last step (NTSC generally 640x480 and PAL is 640x576) and fill it will black in either photoshop or graphic converter and save it as a pict file

9. open quicktime and import your blank pict file

10. drag in the mpeg segments one after another into the new movie

11. export to mpeg-2 with whatever settings are necessary, keep in mind the size of your ac3 file and leave a little breathing room as well. (this step takes about realtime for me on my DP 800, i.e 2 hours for 2 hours of video)

12. Once you have the new m2v and old ac3 streams you can drop them in DVD Studio Pro

13. make a new track and drag the m2v and ac3 file into the new track.

14. click outside the track in the grey area and dvd studio pro and on the side there will be a option for startup item, make sure to select your track you made as the startup item.

15. choose build disc (NOT build and format) from the file menu.

16. open toast titanium and select DVD from the options and then select the new DVD button at the bottom of the window and choose a name for the DVD.

17. drag the VIDEO_TS folder inside your new dvd and burn

Well, I found out what the problem is: when the m2v file is broken up in 4000 Mb chunks (I made them 2000 Mb files) and are made mpeg files, you need to put them together in quick time. If you look at the points where they are put together, there is a small error there... it's not perfect... so the video timing is messed up just a little bit. I tried puting the the whole m2v file in quicktime, and after about 45 minutes of video, the rest of the movie is stuck on one frame. Does anyone know if there is a fix for that?

From what I know and my experiences is that some movies will drift, and some won't. most of the dvd's I ripped came out fine all except for this one japanese anime dvd (metropolis). That movie stays in sync all the way until the last 30 min or so. It's a little off, but not that bad.
