DVD Lab - Cannot Packetize Audio Stream (???)

[malicedoom]

OK, so I've figured out that my new Sony DVD burner likes TDK DVD-R discs and so does my main DVD player (Toshiba SD-6200). Now the trouble I'm having is getting DVD Lab to compile properly for me.

I've ripped some scenes out of a movie (The Insider) and then brought those ripped VOBs into DVD Lab. If I do NOT let the program demux the file and just bring in the VOB directly, I get no audio when I compile. If I let the program demux the files (where I usually end up with one MPV and one AC3 file), certain scenes will compile properly, but others come back with the CANNOT PACKETIZE AUDIO STREAM message during the compile, and there's no audio on those clips. It happens to the SAME AC3 clips every time, and I've tried ripping those scenes with both DVD Decrypter and Smart Ripper: same result. Also the same result when using the 1.1 and 1.3 beta versions of DVD Lab.

Any suggestions on what I can try? I'd easily pay for DVD Lab if I could get it work properly. Is there another program less quirky at handling this type of thing? I'm simply trying to pull scenes from my DVD collection and make a compilation. Thanks in advance for any help!

I think that DVDLAB still doesn't support AC3 audio. Check the website feature list or the manual for confirmation. If I am correct, then you need to either use a program like besweet to convert the AC3 into WAV or a program like VirtualDUB modification for MPEG-2 and AC3 to save the audio in WAV. You must then compress the audio in MPEG layer II.

It appears that only more expensive programs can handle AC3 audio for DVD authoring (like Adobe Encore)

DVD-Lab supports AC-3.


From DVD-Lab website:

Audio
MPEG, AC-3, DTS, WAV, AIFF is supported. From stereo to 6 channel Dolby Digital, you can use it all.

Yes, it SUPPORTS it, but I think the problem is with the way I'm ripping the DVD... for some reason, the same tracks keep coming out with bad audio (AC3) files... anyone have a good suggestion for a program for ripping DVDs other than Smart Ripper and DVD Decrypter?

It could be the DVD disc itself. See if a friend has the same DVD and borrow it or rent it from a store and try ripping THAT DVD instead. Could be your discs has errors from either a manufactoring standpoint or sometihng like fingerprints, scratches etc.

In fact try cleaning the DVD disc as well as you can to see if that helps at all.

Ok Im having the same problem when I try to author a movie with ac3. it keeps telling me that it can not packetize the audio. I always author movies with ac3 and I never have came across this problem. Any help on this matter would of great help. Thanx

I believe it is the bitrate. What does the asset bin say about the bitrate for the AC3 elementary stream. 224, 384, 4xx, xxx? Also, what is the sample rate, 48 or 96 mhz?

For two channel dolby, 192 or 224 kbs is fine. I need to look up for 5.1.....

And DVDlab muxes AC3 audio just fine!

Well, what are you doing to only rip certain sections of a DVD? Are you ripping at the cell level? If you are I would bet that is the problem.

Try ripping in IFO stream mode and rip the entire movie and demux the video and the audio at the same time in dvddecrypter.

Use a tool like videoredo to pull out a small section of video/audio that you need for your production.
