DVD Decryptor + Womble DVD Video Wizard = bad audio?

Can anyone help me out and tell me if I'm doing something wrong here?

I'm working on an editing project, and I am using DVD Decryptor to extract my audio/video components. When I put the .vob audio files into Womble for editing, I get really weird results.

In one instance, the video and audio for a segment have equal lengths on the time table, but as I click to different parts of the audio (to make sure they match up), they go terribly out of sync, by several minutes even.

In another instance, I took a complete .m2v movie and aligned it with a complete .vob sound track and again, as I click around on the time table this time, it also goes out of sync. After a certain point, the sound just buzzes horribly.

Is there a step to this process that I am missing, or just not performing properly? Is there a better (free) way to rip .ac3 files than using DVD Decryptor? Any help would be much appreciated.

EDIT: I am following ADigitalMan's guide by the way. I was rereading it here at work (I can't access my files right now). It seems to imply that I should demux the video in one run, and then the audio track in a separate one. Is that possibly what is giving me problems - doing both at once?

What is a .vob audio file? An audio file shouldn't have a .vob extension.
Do you use dvddecrypter to demultiplex the vobs (stream processing)?

I tried demultiplexing directly from dvd with dvddecrypter but I sometimes got header errors or something with the ac3 files (I can't remeber exactly, it was a long time ago). So now I always rip the vobs to my hdd and demultiplex them using vobedit. Works like a charm, never had an error.

For some reason, DVD Decryptor demultiplexes the video from the VOB as an m2v, but leaves the audio portion in the VOB. I know - it didn't make sense from me either.

VOBEdit sounds like a great program. You've helped me out once again, Arnie. Thanks for the quick response!

It's amazing how great some of this freeware is. You get a program that isn't even a MB in size, and it can manipulate huge files for great results.

Because you didn't click the correct radio button. You have probably clicked on demux when you selected the video stream, but when you've chosen the audio stream, you've left the radio button on "direct stream copy".

To be fair, I ripped some audio tracks today and was frustrated by that niggling radio button process. I had to go through 10 different tracks and select the 'demux' option for all of them as opposed to what would be ideal: shift-select the 10 tracks and then click a 'demux' radio button. It's an area I always thought could be improved. But they've stopped updated Decrypter haven't they (due to all the legal stuff)?

DVD Lab Pro has a demux feature whereby if you drag the first VOB in the stream, it will demux all video and audio tracks in sequence through the VOB titleset. If DVD Decrypter is a little hard to figure out, this may make it much easier.

Yep - you're right. Thanks for the heads up!

By golly, I was going to put this tip into ADM's thread, but forgot. Saved me some carpal tunnel syndrome when ripping extras discs:

Change the default to Demux:

Tools -> Settings -> Stream Processing Tab

Put an asterisk in the demux box.

(IIRC, you have an asterisk to clear in one of the others).


It's been a while since I ripped, but I think that's the option that it forgets to obey, every so often. So you have to check to make sure.

One day I found... 10 years had got behind me. Next day was worse.
