Adding a downmixed audio track to a DVD ISO

[mjf]

I would like to add an audio track to a movie DVD ISO.
My problem is that to play iso versions of my video DVDs using a WD TV Live Media player. Unfortunately many of the DVDs only have an ACR3 5.1 for the main movie audio and WD do a bad job of down mixing to stereo which is what I need.

Handbrake seems to be able to do exactly what I want but for mp4 and mkv.

Is there any software to add a stereo down mixed track and get a playable ISO with the 2 audio tracks?

Add: I'd stress they are my paid for DVDs which haven't had a stereo track included.

Is this just a very difficult thing to do?

Well, kinda, yes.
Replacing audio streams from a DVD ISO means that you would need to decrypt the DVD, separating the audio and video streams, then process the audio into the format of choice and then burn the DVD to ISO again.

DVDFab HD Decrypter can help you with the first task, and I find that the AC3Tool is a great resource for manipulating AC3 files; you can downmix it do a 2ch WAV file and do whatever you want with it. Just note, it must be run elevated (run as admin).

Try Freemake Video Converter.

It may not take the ISO, but you can mount it on a virtual drive and it should take it. Convert DVD to DVD . Choose destination as ISO. You must get a DVD ISO with Stereo sound if what the screenshot tells is true. Hmmmm.... You may not have much control on various parameters (except the ones in blue). It is all simple click, click,click. ( I only explored the possibility and did not run the trial )



There may be other Video Converters which may do the same with better control on various parameters. You may have to check and try. Try XMedia Recode.
