View Full Version : VOB has no audio says VRD

August 8th, 2006, 07:13 PM
I have a DVD on my hard drive in VOB format.

It will play OK with PowerDVD, Media Player Classic & WMP, however VRD reports no audio whatsovever.

It has in fact three tracks at AC3 Dolby Digital 6.1 @ 384

Nomally I would trim 30 megs from the front of the VOB and upload it but on trimming the 30 megs this results in the sample having no audio under any player.

I can upload the complete VOB of nearly 1GB if you like suiteably rar'ed.

Using VRD 482

Try enabling "Ignore TS Maps" in Tools>Options>Stream Parameters

Ignore TS Maps make no difference I'm afraid.

Try uploading the smaller trim and copy segment. We will evaluate it. Don't bother to RAR it. Video files don't shrink that much.

Could you trim and copy a 30-50MB segment of the original file and upload it to us? Tools>Trim and Copy Source File

Confirm that the trim and copy segment has the same problem before uploading.


Create a folder with a unique name and place the file in it.

Send an email to Support@VideoReDo.com and let us know when it has been successfully uploaded.

Also include a reference to this topic number 2878

Pat, wouldn't it make it easier for tech support if the folder for the upload were named with the topic number?

I have uploaded a 40MB sample called No Audio.vob in folder Topic 2878

Awaiting your findings...........

Yes it would, however, some of our users are novices and inexperienced with FTP or file/folder renaming so any name they choose for the folder is OK and we can always rename it. (As long as we know where and what it is.)
