"Play All" caused audio out of sync (DVD Lab Studio, Half-D1)

[iryu]

Hi all,

I created a DVD from 2 VCDs, avoided the re-encoding (it's Half-D1 DVD), and I used DVD Lab Studio to author the DVD. I used "Advance Menu" option that provided me with "Play All".

I split the original MPEG1 file using TMPGEnc MPEG tool, and then I use BeLight to transcode the *.MP2 audio to *.MP2 with 48Khz sampling.

On the DVD menu there are 3 links:
1. Play All
2. Movie1
3. Movie2

The "Play All" will play Movie1 and then followed by Movie2.

When I select/play Movie1, or Movie2, it works fine.
But the problem is, if I select "Play All", the audio become out of sync (it's about 1 - 1.5 second late).

Does somebody know what this problem is? I would really appreciate any help.

Thanks.
Iryu.

Hi there.

Have you tested the DVD on a standalone? on a software player?
on several software players? on several SAPs?

Without having more details, I can only suppose that perhaps your SAP
does not support very well the "Play All Titles" feature. Well, at least
I know for sure that my old LG does not support one of the three types
of playlist offered by DVD-lab Pro (fortunately it's not the "Play All" one).

Hi Midzuki,

Sorry I just had a chance to try it just now (just got back from out of town).

It had the problem when I tested it on a SAP, SuperSonic brand.
When I tested it on my other SAP (Philips brand - the cheapest one sold by Wal-Mart), it works fine.

Do you have any suggestion, how to make a "safe" playlist that's compatible with all SAP?

Thanks.

I may stand to be corrected, but I don't think there's a way to guarantee playability with all stand-alones short of pressing discs - and even that might not do it.

There are ways, however, to maximize your efforts: Use Verbatim or TY brand discs (Verbatim only for dual layers) and burn with IMGBurn. I usually burn at lower speeds that max recommended too. The way I figure it, what the Hell good is a nice, fast burn if you can't do anything with the disc (short of using it for a coaster or frisbee) after it's burned.

Mpg audio is NOT within the dvd specs for NTSC dvd's.

I'm not sure if that would cause such a problem as i have never had or seen this problem, but then i only use DD/AC3 or DTS for dvd's.

For dadrab:
Actually it plays well, I don't have any playability issue. It's just when I select "Play All", the audio become un-synced.

For Noahtuck:
Great idea!! I should try to encode the audio to AC3 first before authoring the DVD. I'll post an update.


Anybody else have different ideas?
I never have any problem with the Supersonic SAP I have. Even if I select "Play All" for commercial DVD, it works fine. It's just it has a problem with "Play All" mode of the DVD I authored.
