How to raise the volume on a dvd?

I have an older DVD that I copied with DVD Decrypter and the volume output is very low. It is an AC3 2-ch audio file. I have extracted the audio file with DVD Decrypter and was hoping someone can tell me how to raise the volume and reauthor the dvd with the new volume file. There is no setting on my dvd player to raise the volume and the volume on my tv is set very high. If someone could give a detailed guide on how to do this it would be greatly appreciated.
Thank you very much.

There could be so many reasons for this low volume audio track. To get some meaningful advice you should upload the audio track (or at least a part of it) to some file sharing site.

In short the volume could be just too low so it could be raised in a linear way so the highest peaks would end up at 0dB (or slightly lower), which would not affect the dynamic range. If this does not achieve the desired result then you need to apply real dynamic compression. The possibilities are endless, reaching from high end studio plugins to quick and dirty online audio manipulation like https://russellgood.com/audio-tools/ .

Sorry, but this is a far too simple approach. Most likely you will end up with a result which contains heavy clipping.

Please have a look at this post (plus the following ones):

Normalizing the audio is the easy part here; most audio editing software can handle that.

What OP is asking about is how to then re-insert the normalized audio stream back into the DVD. Yes, it is possible, but it is not an easy process to do it correctly. IIRC, you have to use PgcDemux to retrieve the CellTimes, re-author a different disc with the new audio file just to get a VTS of the title, use Vobblanker to zero out the original title on the original file structure, and then add the new VTS in while using the CellTimes for...something (it's been so many years that I don't even remember if I'm mixing the workflows of two different tasks here). Then regenerate the entire DVD structure, and hope you did it correctly and the result is acceptable to your DVD player.

It would be far, far easier to just encode to a video/audio format that the set-top box or other hardware (video game console, HTPC, whatever) can play back over USB, than to try to go through all of that.
